I have old Dolfi family ties from Crespole, Comune di Piteglio, which is not far away - Caterina Dolfi b. ca 1747 married to Giuseppe Paperini b. ca 1765. I don't have any more information on Caterina, but suspect that she came from the Comune di Marliana, possibly from Montagnana or Momigno and went to live with her husband in Crespole as there were no Dolfi families in Crespole in that time period. I would be interested in learning about your older Dolfi family ancestry to see if I can eventually relate it to mine. I suspect that all the Dolfi families from this area are related (if you go back far enough).
