just discovered my great great great grandfather was enumerated in the 1860 US Census. I'm pasting the information I have below in hopes of connecting with someone else tracing this lineage. I would love to find Marin Perez's parents, of course. It is an unusual first name, I hope that is a valuable clue.

Marin Perez is listed in the 1860 United States Census on page 317 as residing in San Antonio, Bexar County, Texas. His age was estimated as 22 years old, and his birth year is estimated as 1838. It says he was born in Mexico, but the English speaking census worker probably listed any Spanish speaker as being from Mexico. His two daughters are listed as born in Texas.

Marin Perez’ occupation isn’t indicated, but every other head of household on the same page is listed as a farmer, so it is likely Marin was also a farmer.
Marin Perez in listed as illiterate, but that could mean only that he couldn’t read, or write in English.

Guadalupe Perez is enumerated in the 1860 US Census by her married name on page 317. Her age is estimated to be 20 years old, and date of birth estimated to be 1840, in Mexico.

Maria Guadalupe Perez Hernandez at age one year old is enumerated in the 1860 US Census page 317 along with her parents, Marin Perez and Maria Guadalupe Hernandez, and two month old sister Marcela Perez

Not related, but here is some more info:

Alvino Perez died on 11/23/1945 in San Antonio. He was the son of Marin Perez and Guadalupe Hernandez. He was born 3/1/1868 in San Antonio.

Diego Perez, died on 3/21/1953 in San Antonio. Born 11/12/1886 in San Antonio.

And finally, Innocencia born 12/29/1862 and died 1/16/1958 in San Antonio. She died with the married name of Esquivel (sp?)

One record shows that Innocencia was baptized at San Fernando in San Antonio, so you may want to check marriage records with them.

In the 1900 census, Guadalupe shows up as a widow born April 1840 in Mexico.

Hope this helps!

Thank you Casey.
