1850 Census - Canton, Fulton Co., IL -
Coykendall, David, 26, b. NY
, Betsey, 26, b. NY
, Nathan, 3, b. IL [Deaf & Dumb]
, Charles, 3/12, b. IL
I believe that this David is misspelled and should be Daniel [actually, Joel Daniel Coykendall, b. 1825 Allegany, NY, d. abt 1910 in Minnesota]. In the 1905 MN State Census, Daniel is shown in Alexandia, Douglas, MN with his son's family.
Daniel & Elizabeth [Scott] had:
Coykendall, Nathan [Joel Nathan] 1847
, Charles, 1849 [died young]
, Alice Frean 1852
, Edwin Carroll - April 1854
, William Daniel 1859
Hope this helps,
Sharon
