Margaret Cuffman's "Doubleday Families of America"mentions a J.M. Doubleday of Caldwell, Kansas, as the brother of Harry Austin Doubleday ofElkhart, Polk County, Iowa; Mrs. Ann Mullen, and Mrs. Mary Swaney (both of Westpoint, Indiana).
This J.M. (John M.) would have been the son of Henry L. (Elisha5,4,3,2,Roger1) and Eliza Ann (Williams) Doubleday.
There is quite a bit of information in the book. If you'd like, I'll transcribe it and send it on.
