Looking into the individualRecords of Family Search I read that Isabel Betancourt Cornick ( Alonso/Alonzo Betancourt & Jane Cornick`s daughter) married in 1852 in Cuba,Dn. Mariano Agüero Cisneros. In the tombstone in Philly says that he was born in Cuba , Pto. Principe in june 27th. 1836. and died at Frankford sept. 23rd 1883 Does it means that he was only 16 years old when he married Isabel?
The Family Group Record do not have record of children, maybe because they were already living in Philadelphia..?
