My great great grandmother is Catherine Vlahakis born 1845 in Sparta, Greece. She married my great great grandfather Elias Baliotis (Mpaliwtis) born 1844 in Alevrou, Pelopponese. His sons were photographers, George Baliotis 1877 and Demetrios Baliotis 1877, both of Alevrou. They moved to America in 1904, and lived in Lowell, MA. George married Aggeliki (Angela) Margelou 1887, and Demetrios (James) married Helen. I know almost nothing about Aggeliki, and nothing about Cathering Vlahakis.
the attached photo is Elias Baliotis from about 1940
