Pastos Family

I am visiting Kythira, home of my grandparents, for the first time. I am looking for my Grandfather's home. He left Kythira in, I believe, 1914, but maintained his home until his death. It then went to his daughter. His name was Vasilios (William) Pastos. His daughter was Anna Pastos Katsekes. I have an image from 1954 when my father, Constantine, visited. Old, I know. How can I locate this home! I believe my aunt added on to it immensely, but I would still like to visit. Any suggestions? All my thanks. Connie Pastos Rogers
