All I have on my gr grandmother is Dell Allard. I do have a picture of Dell (Allard)and Raymond Hubert Cooper with there only child Erroll Hubert Cooper, taken in Roseville, Ohio, given to me by my cousin. I know there was a connection to the Johnathan and Jane Allard family but don't know what that connection is yet. It may be possible they were cousin's but your theory sounds better. I have Mabel Allard m. C.H. Willis and a picture of Etta, Ray, Roy, and Mabel on Etta's back porch in Crooksville Ohio.
