There is a stone in the Ellerton Cemetery in Jefferson twp, Montgomery Co., OH for Frederick Heeter, died Jan 10, 1831, aged 75 years, implying a birthdate around 1755. (The other Heeters in the cemetery are Sebastian's son Abraham and his wife Catherine.) Frederick probably accompanied Sebastian's family to Montgomery Co. in 1814. (I should check the 1820 census.) Since all the known Heeters in Montgomery Co. are descended from Sebastian, it is likely that when Frederick came to Montgomery Co., at age 60 or so, he did not bring any family with him.
