Understanding Geni sources and resources

I received a Geni Smart Match for James Godwin, my wife's Wheeler line has Godwin's in fact I am working on it ! How did you connect that line to me ?

I would like to understand more abut your services and how to use them. We also received a Nathan Veatch smart match which is also in my wife's line.

My question is you have little information on my lines how did you attach information on her lines, I would like to understand!

Thanks, Bob
