I was going back through my Stewart line, tidying up profiles and adding more sources, and decided to try to locate some of the offspring who were still alive. I located the phone numbers for 2 of my grandfather's brother's grandchildren, and miraculously got through to them. They in turn gave me the numbers for their sisters. Instantly liked them, had wonderful conversations with them and got a few new tidbits of information to add to Wikitree. Yipee!!
It's funny though. Seems that my Stewart clan didn't know much about their grandparents' relatives, or that they even existed. Several were shocked when I told them their grandfather's had 13 or 14 siblings.
My grandfather was the same way. He never mentioned his family that I know of. Sure wish I knew what happened. Oh, well, I'll just keep digging and see how many other Cousins I can find and contact.
