If your uncle was a former Governor of Guam,he then possibly was the one related to my husband.
From Saipan there is one line of family tree there he is related to Herrera in Guam. He is the brother of Joaquina San Nicolas Babauta her married surname was Herrera. She died, but has sons living in Guam. Check that out. I just recalled this when I read Saipan on your message! They may be your close relatives. David Herrera has posted notes on this site either here or on the Chaco board.
