Your grandfather Delifno is my grandfather also. My father was the last son born in 1935 in Reserve NM "Anastacio Delfino U".
We are 1st cousins.
Robert Lee Johnson is our cousin also and he is the family historian. You can see him posted on the search page. Email me at my home and I will send a photo and you can see if we look alike. Where did you find your info and do you have any photos of our grandfather ?
