Yanos Cassimatis

I am looking for relatives and information about Yanos (could be Yani) Cassimatis who was born on Kythira in 1882. He was my grandfather. His father's name might have been George. I was told George was a Burgermeister in the town where he lived. My father's name was Antony Cass. It was later changed to Anthony Cass. He had a sister named Pearl. Yanos relocated to USA and lived in California.
