This is a very interesting post about the Caban surname. Thank you.
My great-grandmother is Maria Caban (b.abt. 1864 in Quebradillas, d. in 1960 in Camuy) Her marriage certificate to Domingo Felix in 1887 in Camuy states that her father was Manuel Caban who was born in Aguadilla. I have nothing else on him, but I imagine if I could get a hold of the church baptism records, I'd find him.
I've just restarted my genealogy, so I've got a lot to do.
