I need help in researching and creating an Aguilar family tree. My father's name is Fernando Flannegan Aguilar. He was born in Rock Springs, TX in 1919. I believe his fathers name was Santos Aguilar. My grandmothers maiden name was Altagracia Flores. She was from Piedras Negras Mex. I believe. Sadly she died 1921 when my father was 2 years old.
Now here is where it is even harder to trace. My father then went to live with his stepgrandfather who was named Jack Flannegan. Somewhere along the journey he wound up in Las Cruces NM, where he joined the Army. He served in the 82nd Airborne Division 504the regiment F company. He returned from the war and settled in San Antonio.
He has stepbrothers and sisters. Tomas, Pete, Juan, and Agripina Aguilar that I can think of right now.
I would appreciate any help in tracing the family lineage.
