My mom’s father’s surname was Sauceda and I was able to get one of my uncles to submit a sample for paternal line testing (only to the 37th marker, I don’t know if we’ll upgrade). This is what we found:
His haplogroup is E projected subclade is E-M35.1 if we tested more markers. You can click my Haplogroup E-M35.1 tag if you would like to see my older posts on this subclade since it is also my husband’s subclade (Though I think this would change if we tested more markers. His birthday is coming up, so we’ll see.). We don’t actually know anything about grandpa’s father partially because we couldn’t actually find his birth certificate. But we do know that grandpa’s mother was born in Nuevo Laredo, Tamaulipas, Mexico. Grandpa and his brothers were born in Tyler, Texas so his father either met his mother in Texas or Tamaulipas I think.
Anyway, I submitted my uncle’s sample for inclusion in the Mexico DNA Project and humbly ask you to check it out and join. Please. Especially if you suspect any of your lines are Native American because the database needs more samples! This is the description:
“The Genealogy of Mexico DNA Project was started on 9/7/03 and is for those whose Y-dna (father’s father’s father’s…) or Mitochondrial DNA (mother’s mother’s mother’s …) line extends to Mexico or New Spain. This includes the following states prior to 1848; California, Arizona, New Mexico, Texas, Nevada, Utah and Colorado.
I have always wondered about the origins of my ancestors in Mexico. In 1998 I started The Genealogy of Mexico website with this in mind. It has always been my hope that information shared would lead us to the genealogical answers we seek.
With new advances in science it is possible to determine our ancient origins and see who we are related to.
PLEASE NOTE: the following names are names we are researching and may not necessarily be in the project. This research can be found on THIS website. This study concerns all the surnames of Mexico.”
Interestingly, my uncle has a match (although not a perfect match which indicates a few generations have passed since we shared a common ancestor) whose last name is Sancedo. Mr. Sancedo mentioned to me that his father told him the surname had been Saucedo a long time ago but was changed at some point. He doesn’t know why.
