I joined the Daughters of the American Revolution for the genealogy - it is a lineage society, after all. In joining, I utilized their Ancestor Database to find Revolutionary War Patriots to join through. I also pursued their Descendants Database, which is made up of the other generations of ancestors that have been documented to reach the Patriots.
Ultimately, the Ancestor Database and the Descendants Database (which are connected), are one giant family tree, with options to order the documentation used to prove the lineage (see my previous post).
One of the benefits of joining the DAR and having my application approved is that my ancestors are now in the database! It takes a while, as each generation has to be indexed, but there're there. My application resulted in five generations being added to the database, starting with my Great-Grandparents, Bennie Craft and Sally Ruth Evans. I would be so thrilled if one day these generations helped someone break down a brick wall or join the DAR.
Go explore the databases on the DAR website - and check back often. One day a new member's application might help break down your brick wall.
