I am not familiar with DOVENBARGER surname.Henry Eakle b. Feb 14,1775 married a Polly May Poffenbarger and we believe this Henry is a son of Johann Heinreich Ekell. This Henry later married a Febe/Phebe York who was a teen-ager.This was after the death of his first wife. This probably doesn't help you with the surname you are working on. A professional genealogist, Arlene Eakle of Woods Cross, Utah mentions the Eakle line in a book she and Johni Cerny wrote some years ago, titled "Ancestry's Guide to Research." I believe it was published in 1985 by Ancestry Incorporated.It is probably in the library but is probably out of print.
