Social media is a great way to connect with people; people you know and people you don't know. Most families know who their first cousins are, but not second or third. Social media is great way to find those unknown cousins. Hopefully once you connect you share with each other what you know about your common ancestors. Using Facebook to create a genealogy group is a useful tool to get people together who are researching a common distant ancestor. Not only can you tell the group what you know, but you can continue to update them when you find new information.
I recently joined a Sanderson Family genealogy page which focuses on the descendants of Robert, Edward and William Sanderson of Watertown, MA. Already I have gotten new information about my ancestor, William. I also belong to a less active page on the descendants of James and Nancy Thornton. I recently posted and am hoping to get the group more active.
If you are interested in joining either group, contact me and I can give you more information about the groups.
