I don't know your Mary Elizabeth, but I just added a profile for Wyatt Berry Stapp Earp, several good on-line references, and the DAR record numbers for William, Phillip, Joshua, Josiah & Abednego Earp. This isn't really my family, but there is a Cooper-Earp marriage of interest to me, so I decided to see where Wyatt fits in the tree. Please feel free to expand. There is a lot more information in the DAR database from the four patriots listed above. Phillip is Wyatt's line.
