Look for Panaretos Family information

My grandmother's name was Gregoria Panaretos, her brother was Cosmos Panaretos. I was told some other relatives went to Australia. She was born around 1892 Karava, Kythera, Greece. He moved to Michigan. My Yaya moved with her husband John George Rampias to New Bedford, Mass. They had 4 sons. George (my Father), Stephen, Constantine, and Lambros. They are all deceased now. I am the only grandson of Gregoria and John. I am 57 and have two sons, Matthew and Ross Rampias. I am curious if anyone knows of related history and granparents names etc. My uncle and father said they met extended family (Panaretos) family relatives in Australia during WWII>
