Binnie's "Cemetery Records of Paw Paw & Pleasant Townships", p. 48, lists in the cemetery of the Old Order German Baptist Church in North Manchester, a joint stone for Daniel Heeter 1866-1929 and Mary Heeter 1868-1938, and adjacent stones for their children: Chester J. 1898-1918, age 20-11-14; Lydia F. 1899-1918, age 19-3-8; and infant daughter Jan 1886, infant daughter Feb 1887. (From death records, Lydia and Chester died one day apart.) Since the 1900 census said that Daniel & Mary had only been married 5 years, and there are definitely no children born in the period 1888-1895, I am assuming that Binnie misread the stones for the unnamed infants, and they should really be 1896 and 1897.

Wabash Co. Death records, bk. 1925-39, p. 38, lists Daniel Heeter, d. 1-8-1929, age 62. (From index cards only; I haven't checked the record)

There is no marriage record for Daniel and Mary Elizabeth in Wabash Co. Perhaps they married in Kosciusko Co.
