Daniel C. Manthorne was my dad's uncle, of whom he was named after. Eldridge Wentworth Manthorne b. 29 Mar 1871 d. 29 May 1933 was his father and one of Daniel's brothers was Frank Earl Manthorne b. 1 Aug 1915 d. 17 Mar 1966. Frank was my grandfather. I have listed seven brothers and seven sisters (Stella Pearl died at the age of 5 1/2 years). I also have Matilda Tildon Whynot b. 11 Aug 1878 d. 10 July 1964 listed as Daniel's mother.
I have just really started researching by looking through old obituaries and visiting the cemetery.
