Looking for ancestry of GIROLO.

SYLVESTRO (SILVESTRO) GIROLO (b.1843 Andalo Valtellino, Italia - d. 1912 California, USA) married MARIA GIANOLI (b.1847 Italia - d.1889 Como, Italia).

They had five (5) children: PIETRO, MARIA, GABRIELE, ANNA, and ANACLETO. The three (3) sons left with their father after their mother's death to California, USA. The two (2) daugthers stayed with the mother's family.

If anyone know any information about the daughters (Maria and Anna) or about the parents' ancestors (Sylvestro Girolo and Maria Gianoli), it would be greatly appreciated.

Molto Grazie
