seeking information and family history

hello. I am Michael Andronicos. My family originally comes from Kythera, also my grandfather is Charles Andronicos. My family originally established "Andronicus" Coffee some many decades ago, and I am seeking information about my family and ancestors of that era. If you have any information or suggestions which may help me with my research, please do not hesitate to contact me.

Thank-you very much
Michael Andronicos
