Samuel, The only proof I have that Walker is the father of James Youmans(married Martha Cooper) is from Kat LaFrance's info. She found info handwritten by her uncle giving the family linage, including a name that may??? be 6 great plus or minus uncle.
My Aunt Fran had looked for years for parents and siblings of James, even going to the National Archives in Washington DC with no luck.I got the Youmans family history from Tom Yeomans which again ended with my 3 great grandfather James.
When info from Kat showed up I was delighted==and your request and the other gentleman that responded to your info request, is the ONLY other info I have regarding Walker Yeamans.
My line--LLoyd William Youmans, 1907 to 1976, Vestal, NY, married Lela Annis Harrington. Grandfather--Walter NMN Youmans, 1873 to <1945> Broome County, NY married to Myrtle Belle Neal. l great--William Henry Harrison Youmans,born 1842,PA,married LizzieMcClelland. Lizzie born in Ireland 1847. 2 great--John 1811-1859,Tioga Co,PA wife Sarah Johnson.Then comes James Youmans, my 3 great and Martha cooper, then Walker, and his line, the infor mation from Kat LaFrance.
