Hi Tony. Just found this so maybe your research is completed?

My great grandmother is Teresa Canipa, daughter of Lorenzo. A few years ago I was working on the family history with Doug Canepa He was interested in Lazarus, I was interested in Lorenzo. After a few years he said that he couldn't establish any link between Lazarus and Lorenzo. Anyway, family stories are that Lorenzo came from Genoa with Bregazzi family. Lorenzo was a picture framer. If you would like to contact Doug, I have his email address.
