There were 4 Rev. Mannings, Rectors of Diss. Revs William,William,Charles Robertson & Charles Upwood Manning. C.U.Manning had a daughter Ruth Beatrice M.
You can find my extensive Manning Family Tree on Ancestry.ca I am living in Canada. Ruth was my Aunt. C.U.M. was my grandfather.
Please let me know if I can be of any more assistance.
