Hi Martha - your grandfather, Jose, is my 1st cousin 1x removed. Jose is the nephew of my grandmother Casimira Arias. Casimira's father was also a Jose Arias and her mother was Atilana Guera.
You and I are cousins a few times removed.
I've had a very difficult time finding information for the Arias side of my family beyond my great grandfather Jose and his wife Atilana, so if you have any additional info, please let me know!
I do have a very good listing of my great grandfather's Jose's siblings, so feel free to pull those from my family tree...they have been well researched.
