In my Plumlee records I found a Sarah Plumlee born about 1835 in Tennessee who married a KUYKENDALL.This information came from a book entitled "The Descendants of Isaac & Margaret Plumlee", 1991, by J. Randall Hoop.The book is now out of print but you might find a copy in a library or thru interlibrary loan.According to the book, this couple had two children, Anna Elizabeth & John Riley.The other two you mentioned are not listed in the book.Until I saw your query, I did not know the given name for Mr. Kuykendall.Unfortunately, I cannot help much with your Abraham Kuykendall.
Sarah Plumlee was born about 1835 in Madison Co., AR (i.e., next to Carroll Co., AR), a daughter of Denton Plumlee & Martha Mays.Denton Plumlee was a son of Isaac Plumlee and Margaret Bradshaw.He was born in White Co., TN.Two of Denton Plumlee's children, Ransom P. Plumlee and Isaac Denton Plumlee, were both born in White Co., TN, and both settled in the area of Springhill, McDonald Co., MO.You will find them in the 1870, 1880, and 1900 Census for McDonald Co., MO.Isaac is listed in the 1860 Census for this county, but I have never been able to find Ransom in any location in the 1860 Census.
I have Sarah Plumlee in Newton Co., MO in the 1850 Census with her parents.
The Denton Plumlee family moved to Parker Co., TX sometime after 1850.They are in the 1870 Census for this location.
These folks descend from a very large family which came from Virginia to Tennessee, William Plumlee & Phoebe Denton.You will find many references to these people in RootsWeb and other sources such as the Denton Web Page by Sue Montgomery Cook.
Perhaps this will be some help in getting you started filling in the information on Sarah Plumlee.
