Saludos, I am Helping someone for the past weeks, who is searching for her father Jose Serna b. 1920 who lived in the USA but he was from Mexico. She has some Photos, and knows his Cousin was Cipriano Serna b.1896 & Dolores Valdivia. Aguascalientes, Mex.

This is Cipriano's son.

the Account is managed by Xavier Serna Cardenas.. which you can see there is an option to contact him, but you need a paid account. if someone has a Geni.com Account
... I'm hoping someone could use their Geni account to contact him.

This is Cipriano's other Son
Gustavo Serna 1926-2018 He worked in economics and finance as you can see in this story he was accomplished.

If someone has the geni account or knows how to get in touch with any of their living descendants, I hope to forward the jpg fotos she has of her father, what she believes was Cipriano's Family, The writing on the back of the photos indicate they are close relations.
Attached Foto shows her father on the far right. Jose Serna
Thank you David.
