Vicente's Two Families

 

Vicente Antonio Campuzano's first family.

While trying to untangle the relationships and DNA connections descending from my 3rd-great-grandfather Vicente Campuzano and his two families, it is helpful to step back, draw some pictures and look at what we have. An illustration of Vicente's first family with Benancia Gutierrez is above. On Ancestry's Thrulines tool, my Mom and her two sisters have differing numbers of DNA matches descending from the children of Vicente and Benancia Gutierrez, ranging between 54 and 74. Some of these may be half relationships descending from Vicente only, and others very likely are also multiple relationships connecting to branches on our side through Vicente's second family or other currently unknown relationships.

I'm currently working through the self-paced Endogamy and DNA course through YourDNAGuide. It is timely and helpful, as I can now more easily see the problem of multiple relationships and DNA inheritance on this side of the tree. Previously I wrote about Maria Antonia Campuzano, who married Juan Bautista Calles. If my research is correct, Juan's father was Joseph Manuel Calles, and Juan's sister was Maria Manuela Calles (grandmother of my 2nd-great-grandfather Manuel Portillo). Maria Antonia's sister, Maria Teresa de Jesus Campuzano, married Francisco Calles, who is probably connected into Juan Bautista Calles' family. So we have multiple relationships there with sisters marrying men from a likely connected Calles line, and the Calles men also connecting into my Portillo side.

We also have Ygnacio Campuzano, who had a family with Mariana Portillo. Francisco Calles and Maria Teresa de Jesus served at witnesses to the wedding of Ygnacio and Mariana in 1866.

Vicente Antonio Campuzano's second family.

Our line runs from the second family with Maria Concepcion Amado through son Vicente Plutarco Campuzano. Vicente Plutarco's son, my great-grandfather Plutarco, married Manuela Portillo in Tucson in 1923.

DNA in the news: Franklin Expedition sailors identified with DNA

 

Google Arts & Culture. Cresswell, 1854.

A new study has identified four skeletons from the 1845 Franklin Expedition to the Northwest Passage. The English sailors were part of the crew on the HMS Erebus and HMS Terror. The identifications were made using DNA analysis. Two of the men were identified through mtDNA connections to donor matches, and another through YDNA (see study in ScienceDirect, 6 May 2026).

Returning to our shoemaker in Altar

 

Made in Ideogram. Vicente in 1859. Altar, Sonora.

In December 2025 I created a likeness on Ideogram for my 3rd-great-grandfather Vicente Antonio Campuzano, working as a shoemaker in 1852. Vicente had two families, and from the first branch of the family we have a Big Y 700 tester in cousin Greg. His result provided a clear Iberian connection. A Big Y test has come back from the side of the second family, connecting to my own branch on the Campuzano side. The results are not what I expected, and I'm doing some additional analysis - and guided consultation next Monday - to understand how to proceed next.

There are definite hints of a connection to the Portillo side of the tree. I'll be exploring this further, and first need to connect again with the Big Y testers.

Segments in common

 

23andme. Chromosome browser comparison.

I'm continuing to work with DNA data and the chromosome browser tools on FTDNA, MyHeritage and now 23andme. Looking at some DNA matches on the Portillo and Campuzano side of the tree who tested at 23andme, I can see segments in common. I'm exploring a theory that may help resolve a question of multiple relationships, and better place Mariana Portillo on our tree in connection with my 3rd-great-grandfather Manuel Portillo.

Some additional new test information has arrived that calls into question some of what we've thought on the Mexican side of the tree. I'm hoping using the chromosome mapping tools will untangle these complications.
