Mignon - you need to go to FamilySearch.org. This particular family line has a completed genealogy posted back at least four MORE generations!!!

Look under Edmund Richards in NY and then click on pedigree to see the entire chart! The arrows at the end on the far right indication additional generations beyond the last name.

Just be sure you verify their work. You can go to the local Family History Library in Voorhees on Evesham Rd. and make requests for the microfilms to see the actual documents submitted. There you'll see what the source documents were that the researchers used.

Now, if I could just find my mother's and father's surname lines as neatly! LOL

Good luck.
