@Benjamin Andres Garcia - In my experience finding vital records (and especially African American vital records) in Alabama is difficult before the 1930s. If you look in the FamilySearch catalog under Mobile County, Alabama - the birth records don't begin until 1920-1940.
I don't know much about Cuban records but maybe a marriage or death record could be found in the records online (https://www.familysearch.org/wiki/en/Cuba_Genealogy)
Thank you. So far, I have only been able to find my father's (Andres Garcia) Cuban birth certificate, listing his father my grandfather's name Andres Garcia and my Grandfather's parents Andres ? and Ablaena Teresa. And nothing else from Cuban records. From family memories, my grandfather appears to have been a commercial diver and lost his life in a diving accident in Cuba in 1963. He was allegedly born in Alabama in 1897. I have a photograph of his headstone and pictures of him with my Jamaican born grandmother in Cuba. I also have a picture of him, a very handsome guy.
