Hi guys, I was wondering if someone could help me figure out the origin and meaning of my grandparents surnames. The names are: Costalos and maistralis Both grandparents came from the Island of Chios but I believe the Maistralis side originally came from Izmir. I can't find any info on the origins of Costalos but I believe maistralis might be mean "from master" or something similar? Thanks for any help!!!
