Seeking information on family of Mario PONCE of CUBA. Family came from the Canary Islands to Cuba between 1800 and 1940. Believe family ancestry is in Spain - time unknown. However, family members believe their name was PONCE and not of Leon??Many members migrated to US. One grandson(or son?)is Mauricio PONCE (living in South Carolina, US). Any ascendency or descendency info will be appreciated.
