Information is needed on Willis Green Allen, son of John Allen and Margaret Barbara Grimes. He was born 2 May 1838 in KY, probably Grayson County. He married Maggie Gray in Nodaway Co., MO 4 July 1866. On his mother's obituary of 1882 he is shown as living in Kansas, but no specific location. Willis and Maggie had one known child, Zella Allen, born 4 Oct. 1869, d. 14 March 1873. Zella is buried in the Gray Cemetery in Nodaway Co., MO. Does anybody know more about Willis Green Allen?
