Which Cassidy are you related to is it mary? I was reading some of your message boards. there is a Ethel Mary Clark that marries one of the William Cassidy that has me all confused at moment. If i go by the Cary ME Library data base he is related to my James Cassidy. after looking at all the other Cassidys. Its enough to boggle the mind. Hopefully my James Cassidy is really my James Cassidy.
