Francesco Petronio was from Sambiase,Italy.His parents were Francesco Petronio and Marionthonia Cerro. I did find Francesco(b.1873)from Sambiase did return to America several times,and he did remarry.He stated he lived in Mass. for 12-15 yrs. when he arrived in 1921 to visit a brother (Rodofilo Giovanni ?)in Boston, Mass. My father had learned from his dad when he was living that there were relatives in the Boston area, so this does fit. I found too that my grandfather and his mother,Mary Teresa Mantello returned from Sambiase to Connellsville,Pa. in 1907 when he was 2 and U.S. born and Mary claiming she was single and using her maiden name,which fits with family stories that grandpap went to Italy to be baptised and his parents split with Mary wanting to return to her father at Connellsville.
