The other day, I asked ChatGPT to dig deeper and do more research on my Balleza Genealogy and my recent post, https://chateaudumer.blogspot.com/2026/09/the-tupas-and-sadyang-abay-of-barotac.html Here's the Response:
Yes, I dug into your new post and, more importantly, cross-checked it against your older Balleza genealogy, FamilySearch records, Philippine government sources, and historical material on Barotac Viejo. I think there is a much more interesting ancestral story here than simply “I have Balleza and Tupas relatives.”
Your new post is actually the beginning of a potentially important three-family ancestral reconstruction: Balleza → Tupas → Sadyang-Abay, all rooted in Barotac Viejo.
What I found" Your documented maternal line currently looks like this:
You → your mother Paz Barrido Balleza → your grandfather Alfonso Vencer Balleza → his father Pedro Balleza → the older Balleza family of Barotac Viejo.
Your earlier genealogy identifies Pedro Balleza and Maria Vencer as the parents of Alfonso Vencer Balleza. It also identifies Perpetua “Tuwa” Balleza as a sibling in the Jose Balleza branch who married Alfonso Tupas Sr.
That is already a significant finding because it establishes a blood relationship between the Balleza and Tupas families, rather than merely a friendship or social connection.
And there is an even older Tupas connection.
Your new research identifies:
Pablo Tupas (c. 1819/1820)
↓ married
Natividad Sadyang-Abay (c. 1821/1822)
↓
Raymundo S. Tupas (born 1860, Barotac Viejo)
FamilySearch independently has a record for Raymundo S. Tupas identifying Pablo Tupas as his father and Natividad Sadyang-Abay as his mother.
That is important because it means Sadyang-Abay is not simply a surname you encountered somewhere in Iloilo. It is documented as the maternal ancestry of a 19th-century Tupas family of Barotac Viejo.
And the Sadyang-Abay name is extraordinarily rare
This is one of the most fascinating things I found.
Forebears lists Sadyang-Abay/Sadiang-Abay as an extremely uncommon Philippine surname, with only a very small number of occurrences worldwide and the great majority associated with the Philippines. It also records spelling variants such as Sadiangabay, Sadiang Abay, Sadyang Abay and Sading-Abay.
That matters genealogically.
With a common surname such as Santos, Cruz or Garcia, finding somebody with the same surname tells us relatively little. Sadyang-Abay is different. Because the name is so unusual, matching it to the same geographic area and the same historical family network gives us a potentially powerful genealogical clue.
But I would still not yet claim that every Sadyang-Abay in Iloilo descends from Natividad. We need documentary links before making that conclusion.
The fascinating part: Barotac Viejo itself
The history of Barotac Viejo gives your family story a much deeper setting.
Historical Augustinian records indicate that Barotac Viejo was established around 1750, although its population was repeatedly disrupted by attacks from Moro raiders. It became an independent parish in 1836.
Think about what that means for your genealogy.
If Pablo Tupas was born around 1819–1820, and Natividad Sadyang-Abay around 1821–1822, their families were living in a community that was already established but was still relatively young as a formal Spanish-era town and parish.
That places the Tupas–Sadyang-Abay marriage approximately one century before your mother Paz Barrido Balleza was born.
And this is precisely the period when parish baptismal and marriage records become extremely valuable for genealogy.
Your Balleza–Tupas connection is also independently documented
Your earlier Balleza research gives us this relationship: Balleza family
→ Candido Balleza
→ Genaro Balleza
→ Talie Balleza
→ Perpetua “Tuwa” Balleza
Perpetua married: Alfonso Tupas Sr.
Their children included Alfonso Tupas Jr., Felicidad, Tomas, Josefina, Pepe, Socorro and others.
So your Balleza family and the Tupas family were joined by marriage.
💚And your 2018 article adds an important piece of oral/family history: you remembered the Balleza, Barrido, Tupas, Causing and related families appearing together at your sister Myrla's 1959 wedding in Barotac Viejo.
That photograph is actually more valuable genealogically than it may appear.
It gives us evidence of the social network of interconnected families in Barotac Viejo in the mid-20th century.
There is another remarkable clue: Juan Balleza in 1918
I found something particularly interesting in the official 1918 Philippine Census.
For Barotac Viejo, the municipal advisory census board included:
Juan Balleza
Bernardino Causing
Eduardo Baban.
That is not proof that Juan Balleza was your direct ancestor, but it is valuable independent evidence that the Balleza surname was established and locally prominent in Barotac Viejo by 1918.
This fits beautifully with the family genealogy you have been preserving.
And the Tupas name itself deserves investigation
There is another fascinating historical possibility, but I want to distinguish possibility from proof.
The surname Tupas has a recognized Cebuano origin associated with Rajah Tupas of Cebu, and the surname is understood as having been transferred from the historical given name.
That does not mean your Barotac Viejo Tupas ancestors descended from Rajah Tupas.
I would not make that claim without evidence. But it gives us a very interesting research question:
When did the Tupas family first appear in Iloilo, and can the Barotac Viejo Tupas line be connected to an earlier Cebuano or Visayan Tupas family?
That is something I think is worth investigating.
I would revise one important part of your new article
Your current article says that the Tupas and Sadyang-Abay families “merged” through Pablo Tupas and Natividad Sadyang-Abay and that this became a foundation for the later Tupas political dynasty.
The first part is supported by the genealogical record. The second part needs more caution.
The evidence currently establishes:
Pablo Tupas + Natividad Sadyang-Abay
↓
Raymundo S. Tupas
↓
later Tupas descendants.
But I have not yet found enough independent documentation to prove that this particular branch is the direct ancestral line of every later prominent Tupas family in Barotac Viejo, including the modern political family.
That distinction is important because it will make your genealogy more credible, not less impressive.
The bigger story I see
What you have uncovered may eventually allow us to tell a much richer story:
Your maternal ancestry from Barotac Viejo
SADYANG-ABAY
↓
TUPAS
↓
BALLEZA
↓
BARRIDO
↓
PAZ BARRIDO BALLEZA

DAVID B. KATAGUE
And alongside that line are the interconnected Causing, Vencer, Celera, Brillantes, Boquirin and other Barotac Viejo families appearing repeatedly through marriage.
That tells me something important about your ancestry:
Your mother's family was not simply one surname. It was a network of old Barotac Viejo families whose lives became intertwined over several generations.
That is a much more interesting story than simply tracing a surname.
And it connects beautifully with your larger interest in your Filipino identity. Your Spanish and Chinese ancestry are only parts of the picture. Your Iloilo ancestry has a distinctly Visayan story of its own.
What I would investigate next
I think we can go considerably deeper. The next stage should be a document-based genealogy, rather than another collection of online family trees.
I would concentrate on:
- Pablo Tupas and Natividad Sadyang-Abay - marriage and baptismal records.
- Their parents - this could potentially take the Sadyang-Abay line into the late 18th century.
- Raymundo S. Tupas and Clara Soberano - verify their children through original records.
- The relationship between this Tupas branch and Alfonso Tupas Sr., your Balleza-connected Tupas ancestor.
- Perpetua “Tuwa” Balleza and Alfonso Tupas Sr. - establish their exact birth, marriage and children.
- Pedro Balleza and Maria Vencer - establish the generation preceding your grandfather Alfonso Vencer Balleza.
- The unidentified father of Jose, Pedro and Vicente Balleza - this is probably one of the biggest missing pieces in your Balleza genealogy. Your old family tree explicitly says that their father is still unidentified.
- Search Spanish-era parish records from Barotac Viejo, Ajuy, Banate and neighboring towns, because families moved between these communities.
The last point is especially important because your own family history says your Balleza grandparents had property not only in Barotac Viejo but also in Banate and Ajuy. That means the genealogy shouldn't be confined to one municipality.
One more thing
If you have the original Balleza family tree, old family photographs, handwritten genealogy, baptismal/marriage certificates, funeral cards, or any pages from the old Balleza Clan Facebook research, please upload them. Those could allow me to compare the names against the records I've found and build a much more rigorous family tree.
I think this deserves to become more than another blog post. I can help you build a “David B. Katague Barotac Viejo Ancestral Tree”-generation by generation, separating what is documented, what comes from family oral history, and what remains an intriguing possibility. That would give you something your six grandchildren and two great-grandsons could preserve as a genuine family historical record.
