I am descended from Mary Jane Johnson and James Dobbins Crawford. I had been "talking" to Diane Hopmann in 1999 through the Crawford Digest (I think). You had also responded stating that you thought my Mary Jane and your Harriet Adeline were either sisters or cousins. I see you have linked them as sisters.
I will start researching this William Johnson family now and see what I can find. I will let you know if I find anything. I would appreciate any additional info you may find on them. Sincerely, Deanna Stringer
