Hallo Andrea und Bob,
I found Johann Heinrich Carl Miehe, * Isernhagen 1822 - Apr - 9.
He was a wheelwright and married 1857 - Apr. 14 (Hannover)-Bothfeld
Maria Louise Behre, * Bothfeld 1828 - Jun - 12
His parents were Johann Heinrich Carl Miehe and Cath. Dor. Meier.
Maybe there is a connection to your Miehes.
Regards
H. Miethe
