I was born in Rapsani in 1954, I lived there for 25 years and I visit Rapsani often since it is a nice place. I knew a family with the name Triantafillou, they moved to Larissa around 1970. The Triantafillou family had 2 sons the oldest was a year older than me and the younger 2-3 years younger, I believe the younger died in a traffic accident. I met both the father and the grand-father.
Hope it helps.
