I just saw your post from 1999. Hope you are still checking this board!
I also descend from Elijah Duggins and Rachel Foster. I've just begun researching this line and, like you, have found it to be a Brick Wall! I've been able to get quite a bit of info on Elijah's ancestors...but NOTHING ON HIS DESCENDANTS. A family member gave me an old letter (1929)that went out to the heirs of "another Elijah Duggins" (an ancestor of our Elijah) and it listed the children of "our" Elijah & Rachel Foster as follows:
(1)D.B. Duggins, wife Alice (2)G.W. Duggins, unmarried (3)Emma Booth, unmarried (she MUST have married a Booth?) (4)Rebecca Gaddie, husband: N.L. (5)Maggie Andrews, husband: L.N. (6)Ephriam Duggins, wife Lillie (7)David Duggins, unmarried (8)S.S. Duggins, dead (9)Cora Bass, husband ____Baggett (10) Sarah Barrow, dead (11)*Johanna Mayfield, dead (*MY ANCESTOR)
As I said, this was postmarked 1929 but I've been unable to locate any of those names in census records prior to that date. Of course, if they'd used names instead of initials it would have helped!! Somehow, I figured out that #1 on the list was named Daniel Benjamin Duggins, but I may be wrong. (Can't recall where I got that...I've had the letter for several years but only started Duggins research this week). I do have a photo of Rachel Foster, mother of my Johanna Duggins...sure wish I could find a photo of Johanna!
I hope we can exchange info! I see that you started in 1999, maybe you've learned lots since then!
