I realize you posted this years ago and therefore may not see my post, but I figured I'd try anyway. I was googling "Kanavos" because I do not really have any information about that side (my dad's) of the family. My grandfathers name is Nicholas Kanavos (though he changed his last name to Davis), I know he has a sister named Stella and my father's middle name is Ernest. They all used to live in the Boston (Wareham) area as well. It just seemed like we had a lot of similarities name and location-wise. I was wondering if you found anything out?Perhaps we are even related!
