Our family comes from a long list of interesting people. Some of those families have larger organizations as well. Like this one that was highlighted in a recent Church News.
Joseph Knight Family Organization
The web site has a brief history of the original family and a place to register as a descendent. Joseph Knight Sr. is my 4th Great Grand Father, through his daughter Anna, so you can adjust your relationship from there. They were the original Colesville branch of the Church.
