Descendants of Krom Luang Seni Borirak, son of the Wang Lang · Rattanakosin Era
Preserving a Rattanakosin royal lineage through sourced public history
The Seniwongs Na Ayutthaya lineage descends from Phra Samphan Wongse Thoe Phra Ong Chao Taeng, Krom Luang Seni Borirak, son of the Wang Lang / Krom Phra Ratchawang Bowon Sathan Phimuk. Public copy on this page distinguishes sourced claims from family-history details that remain under review.
Phra Samphan Wongse Thoe Phra Ong Chao Taeng, Krom Luang Seni Borirak, is reported to have been born on July 20, 1777 and to have commanded royal trading junks to China under Rama III. The count of 75 children is kept as an under-review genealogical claim rather than a settled public fact.
See chronology contextHis father, Krom Phra Anurak Thewet, held the Wang Lang / Rear Palace title in the reign of King Rama I. Public descriptions connect that status with early Rattanakosin military service, but this site avoids overstating a single cause without a primary citation.
See chronology contextThe suffix 'Na Ayutthaya' (ณ อยุธยา) was decreed by King Rama VI on April 6, 1925, linking all Chakri royal surnames to the ancient Ayutthaya Kingdom (1350–1767), from which the dynasty traces its noble origins.
See chronology contextPublic secondary accounts report that Krom Luang Seni Borirak took part in the Vientiane / Anouvong campaigns of Rama III's reign and connect that service with his elevation to Krom Luang rank in 1832. The wording here distinguishes participation from sole command.
See chronology contextM.C. That / That is supported by a public monastic biography, which records his ordination, Mahanikaya affiliation, and later Somdet Phra Phutthacharya rank. This claim is retained with that citation.
See chronology contextPublic memorial volumes and records document later Seniwongs descendants in military, government, and academic service. Living or recent descendants are included only when the information is public and appropriate for a heritage site.

This timeline separates Ayutthaya background, the Wang Lang title, Krom Luang Seni Borirak, the Vientiane campaign, the Na Ayutthaya surname marker, and modern public records so readers do not treat them as one event.
The Na Ayutthaya suffix is a modern marker referring back to Ayutthaya as dynastic background. It does not mean the Seniwongs line itself began in the Ayutthaya period.
Ayutthaya served as the capital of Siam for over 417 years, with 33 kings reigning in succession, before its fall in 1767 when Burmese forces captured and destroyed the city. Ayutthaya is a major historical and cultural reference point for many royal lineages, and the Chakri dynasty drew on it to establish dynastic legitimacy in the Rattanakosin era.
The Na Ayutthaya suffix was granted under King Rama VI in 1925, following royal surname legislation, to allow Chakri royal lineages to acknowledge Ayutthaya as their dynastic background. Na Ayutthaya is therefore a modern marker established in 1925 — not evidence that the lineage itself was founded during the Ayutthaya period.
The Seniwongs Na Ayutthaya family traces from Krom Luang Seni Borirak, born in the early Rattanakosin period (1777), not from Ayutthaya (1350–1767). The Ayutthaya reference is a Rama VI-era court convention and should be kept separate from the family's actual founding-generation history in early Bangkok.
Based on public contextual articles on the Na Krungthep and Na Ayutthaya surname system. A specific Royal Gazette issue has not been independently cited.
In 1785 CE, Burma launched a massive nine-pronged invasion of Siam during the reign of King Rama I. The Wang Lang (Krom Phraratchawang Bowon Sathan Phimuk / Rear Palace) played a key role in the kingdom's defence, connecting directly to the founding line of the Seniwongs Na Ayutthaya family. This context belongs to early Rattanakosin history and is kept separate from Krom Luang Seni Borirak, who was the son of the Wang Lang holder.
In 1785 CE, the Burmese Konbaung dynasty launched its largest offensive against Siam since the fall of Ayutthaya in 1767. Nine Burmese army columns attacked simultaneously from the north, west, and south. King Rama I personally commanded the Siamese defence and repelled all the invading forces. The victory consolidated the security of the new Rattanakosin capital and is considered a defining moment of the dynasty's first reign.
The 'Wang Lang' (Rear Palace / Krom Phraratchawang Bowon Sathan Phimuk) was the second-ranking royal position after the Uparaja (Front Palace / Crown Prince), with responsibility for the rear administration and a significant military role in times of war. Krom Phra Anurak Thewet was appointed to the Wang Lang title in 1786, following his involvement in the Nine Armies War. He was a grandson of King Rama I and the father of Phra Samphan Wongse Thoe Phra Ong Chao Taeng, Krom Luang Seni Borirak — the founding figure of the Seniwongs Na Ayutthaya lineage.
The Seniwongs Na Ayutthaya lineage descends directly from the Wang Lang holder who served during the Nine Armies War. Understanding this military and court context is therefore essential for reading the family's early Rattanakosin-era standing. The information in this section draws on public secondary sources and is kept separate from details about individual family members that remain under review.
Based on public secondary sources and cultural-history context. Primary court records have not been independently verified for all details.
Phra Samphan Wongse Thoe Phra Ong Chao Taeng, Krom Luang Seni Borirak (1777–1834), was the son of the Wang Lang holder (Krom Phraratchawang Bowon Sathan Phimuk) and a grandson of King Rama I. He is the founding figure of the Seniwongs Na Ayutthaya lineage. Birth date, child count, and office details remain at reported-source level.
Phra Samphan Wongse Thoe Phra Ong Chao Taeng, Krom Luang Seni Borirak, is reported born on 20 July 1777. He was the son of Krom Phra Anurak Thewet — appointed Krom Phraratchawang Bowon Sathan Phimuk (Wang Lang) in 1786 — and therefore a grandson of King Rama I. His rank as Phra Samphan Wongse Thoe reflected his position as a second-generation royal descendant in the Chakri dynasty. The birth date appears in public secondary sources and should be treated as reported rather than confirmed by a primary court record.
Public records describe Krom Luang Seni Borirak commanding royal trading junks to China during the reign of King Rama III, forming part of the court's international trade activities. Secondary sources also link him to the Vientiane / Anouvong campaign (1826–1828) and connect that service to his elevation to Krom Muen in 1807 and Krom Luang in 1832. These details are reported from secondary and family-history sources; a primary court citation has not been independently verified.
Family-history sources report 75 royal children, forming the basis of subsequent Momchao, Mom Ratchawong, and Mom Luang descendants who have served in the military, government, academia, and cultural life. One son, M.C. That, entered the monkhood and reached the rank of Somdet Phutthachan in the Mahanikaya order — a publicly verified record. The child count of 75 should be read as a lineage-register figure still under review line by line. The Na Ayutthaya surname suffix was granted by royal decree under King Rama VI in 1925.
Based on secondary and family-history sources, including National Library of Australia catalogue records, public articles, and memorial volumes. Birth date and child count have not been confirmed by an independent primary court record.
A public secondary article reports the Krom Muen rank in 1807 and Krom Luang rank in 1832. Treat this as reported until a primary record is cited.
Public secondary sources report that Krom Luang Seni Borirak received the Krom Muen title in 1807, during the reign of King Rama II. This information comes from secondary sources only and has not been verified against a primary royal decree or Royal Gazette entry.
The same secondary source reports the Krom Luang elevation in 1832, during the reign of King Rama III, linking it to service in the Vientiane / Anouvong campaign. This connection remains at reported-source level until a primary court citation is independently confirmed.
Both title elevations derive from a public secondary article (MGR Online, 24 May 2019). That source confirms the information circulates publicly; it does not constitute final historical verification. Both should be presented as 'reported' and avoided as confirmed fact until a Royal Gazette or primary court record is cited.
Source: MGR Online, 24 May 2019 — a secondary article confirming public circulation, not final verification.
Campaign wording should distinguish participation or association from sole command or victory unless primary evidence supports the stronger framing.
The Vientiane / Anouvong campaign was fought between Siam and Chao Anouvong of Vientiane (Lan Xang) in 1826–1828, during the reign of King Rama III. Siamese forces successfully suppressed the rebellion and consolidated control over former Lan Xang territories. It is a defining military event of the early Rattanakosin period.
Public secondary sources link Krom Luang Seni Borirak to this campaign and connect that service to his Krom Luang elevation in 1832. Wording should reflect 'reported participation' rather than 'sole commander' or 'victor', as the specific nature and scale of his involvement have not been confirmed by a primary military record.
This information derives from secondary sources. No primary court document, military record, or first-hand chronicle specifically naming his role has been independently verified. Avoid characterising him as the sole commander or decisive actor in the campaign until primary evidence supports the stronger framing.

Na Ayutthaya belongs to the modern royal-surname framework of Rama VI's reign and should be separated from early Rattanakosin lineage origins.
King Vajiravudh (Rama VI) introduced royal surname legislation requiring all Thai subjects to take a surname. For Chakri royal lineages, specific suffixes were established — Na Krungthep for those closest to the reigning king, and Na Ayutthaya for lineages claiming Ayutthaya as their dynastic background. The Seniwongs family received the Na Ayutthaya suffix in 1925.
Na Ayutthaya translates as 'of Ayutthaya' and serves as a symbolic link to Ayutthaya as dynastic background — not as evidence that the lineage was established during the Ayutthaya era. The Seniwongs family traces from Krom Luang Seni Borirak in the early Rattanakosin period. The Na Ayutthaya marker is a 1925 modern convention, not a medieval lineage claim.
The Seniwongs lineage timeline begins with Krom Luang Seni Borirak (1777), not with Ayutthaya (1350–1767). Keeping these two periods editorially separate ensures readers do not conflate the modern surname convention with the family's actual founding generation in early Bangkok.
Based on public contextual articles on the Na Krungthep and Na Ayutthaya surname system. A specific Royal Gazette issue should be cited before making legal-detail claims.
Modern descendants should be included only when information is public, sourced, and appropriate for a heritage site. Living-person and family-private details remain outside public copy.

Personal details of living family members fall outside the scope of the public pages.
Examples meeting the public-record standard include Lt. Gen. Thak Seniwong Na Ayutthaya, whose memorial volume is accessible through the Parliamentary Digital Library, and Somdet Phra Phutthachan (M.C. That), whose biographical record appears in the Sangkhathikan database. Both are presented with source citations.

This section separates checkable facts from a marriage-link claim that still needs person-specific documentation. It avoids presenting the Seniwongs line as a primary direct bloodline from King Taksin's sons or daughters unless stronger evidence is added.
Krom Luang Seni Borirak is presented as the founding figure of the Seniwongs Na Ayutthaya line through the Wang Lang branch of the Chakri royal family.
The claim that Princess Sali/Samli, a daughter of King Taksin, was a consort of or closely connected by marriage to Krom Luang Seni Borirak should remain marked as under review until a specific genealogy or primary source is found.
King Taksin is widely described as having Teochew Chinese ancestry through his father, making Chinese-Siamese networks an important context for Thonburi and early Rattanakosin history.
Evidence status: Taksin's Chinese ancestry is broadly attested in historical summaries; the claimed Seniwongs connection through Princess Sali/Samli remains pending until a lineage record, royal genealogy, or official notice is identified.
