sssteltenpohl on Family Tree Circles

Ok so I will start a journal. Thanks to the people on this site I now have more info. about my grandfather and great grandfather.
Grandfather: Walter William Allen B. May 15 1890 M 1.Velma Skinner 2.vivian Violet Ruble (Allen,Folsom)
Gr Grandfather: Frances M Allen B. 1856 in Ohio M.Nancy Sarah Hooker.
Gr Gr Grandfather: William D Allen B 1829 M.1. Almira Richardson 2. Charity S Ogden (Hooker)
The Census of 1870 shows that Francis M Allen was living with Asa Richardson I believe this to be Almira's father and his wife(who turned out to be Sally P Richardson formerly married to Joseph Richardson, her maiden name was Allen.} Not unheard of for a child to live with the grandparents after the mothers death. I have found out quite a bit about the Richardsons,but I have hit a road block once again with the Allens. Who is William D parents and is Sally P related? These are questions I look for answers to everyday. If anyone has any info it would be greatly appreciated.
