My great grandmother was Basilisa ALVAREZ GIRAU. She lived in Camuy (two towns away from Isabela). She was married to Juan Brusi Font. Both of them were born in Spain (town of San Feliu de Guixols, in the province of Gerona). I do not know my great grand mother had any siblings. She was born in th 1840s
There was another ALVAREZ GIRAU in the town of Yauco (SW part of the island). Her name was Rosario. In the 1910 Census she apperas as 47 years old.
I just found out that Rosario ALVAREZ GIRAU was my great grandmother (Basilisa) sister. Basilisa apperas listed in the 1910 census.
