I have been helping a friend do his family research. His GG grandfather Antonio married Maria Checo. Marias' parents were Mauro Michele Checo and Maria Illuzzi. Mauros father was Niocola Checo born abt. 1746 in Giovinazzo, Italy and his mother was Vittoria Bavaro born abt.1755 in Giovinazzo Italy. So he has Bavaro blood in his family line!
The Bavaro name was first found in Calabria,and also in the town of Vibonati,located in the region of Basilicata. He can be contacted at firstname.lastname@example.org
