Albert, Thanks for sharing your information with other Losoyas.My husband has Losoya in his maternal line. But his Losoya married into the Sigala family. And before that it was into the Bailon family and that is where I am stuck-about 1840.I found all this info in the pilot site and now in the new beta site of familysearch.org.
I have Faustino Losoya md to Dolores Bailon. They had Bacilia Losoya md to Tiburcio Sigala, who md in 1876 in the General Trias area.
