Gaetano Garzia

[josephinemartinez]

Help!!! I am trying to find out the names of my great-great-great grandfather's parents. My great-great grandfather's name was Gaetano Garzia, born in Caltinasetta Sicily in 1819. His wife's name was Rosaria Costa, also from Caltinasetta Sicily. The name Garzia originated from Spain. I am wondering how much further back I would have to go to find out what part of Spain we are from. I would appreciate any information, links, etc. Thank you.
