My grandmother was Katherine Petro Spiro Vlahos, she married Michael Petros Hios. They lived on the mainland of Greece in the village of Vourvoura, which is between Tripoli and Sparta. Katherine had at least one female sibling, and I am trying to find out more about her Vlahos family. If anyone has any ancestors from Vourvoura, or nearby, named Vlahos, please contact me.
