I went on genes reunited a fair few years ago to try trace my family. Long story but my dads whole side basically died in a haze of Irish alcoholism and general merriment (it's genetic - not my fault).
Anyway, I gave up because I had no idea how to do anything anyway and landed up forgetting about it completely.
A few years ago - about 6 years ago, I had this random message from an elderly gentleman living in Scotland who was wondering if the surname of my great grandmother could in anyway be related to XXX person that he was researching. While it's not close relative, he turns out to be my dads uncle - a great uncle to me that I didn't know I had. Living in Scotland.
Still haven't met him but exchange emails and letters and photos. His daughter developed fibroids recently (at 46) and we exchanged emails on health advice.
Me? I would get in contact. You don't have to blurt it all out on the first email but you could open the door for them. They have a right to know as well - imagine knowing that someone out there knew the wear-abouts of a sister or child and chose not to tell you?
