Patti, I agree with Eileen; Martha Jane was very likely b. in Loudoun Co., VA, the dau of Cornelius Bennett Wynkoop & Martha F. Harden. Most of the names you mentioned from the photo appear to be Martha's nephews and nieces; the children of her brother John Thorton Wynkoop & Ida V. Borid, m. 2 Sep 1879 in Saline Co., MO (Missouri Marriages, 1851-1900). From census data I have the family as: 1) William J. Wynkoop m. Leslie ?; children Wilda, Henry 2) Laura L. Wynkoop 3) Adalbert M. Wynkoop m. Verda ?; children Opal, Anna P. 4) Susie M. Wynkoop 5) Maud L. Wynkoop 6) Amos A. Wynkoop m. Tina J. ? 7) Martha B. Wynkoop 8) Annie R. Wynkoop 9) John T. Wynkoop 10)Merle D. Wynkoop 11)Morris Wynkoop 12)Muriel Wynkoop 13)Inga Wynkoop 14)Mary E. Wynkoop
John Thorton Wynkoop was the grandfather of Carol J. Fite. She has two posts to the ancestry.com WYNKOOP board and you should be able to retrieve her email from there if you want to contact her for more detailed info.
