Hi, your great-uncle is my grandfather so that makes us, what cousins? :) Would love to exchange info. if you're still using this board. I'm new to this & noticed another message you wrote in 1999 but am not sure how to access it so haven't seen the whole message - mentions Theo & a Constantine?
I've attached a picture of the silk handkerchief Theo had w/ him when the Lusitania went down. (The numbers are wrong as I later found out)
