i found a death certificate which reads:
The hairdresser Heinrich Georg Mohr (maybe the son) reported that
Heinrich Mohr, hairdresser, born in Wetzlar, Kreis Hünfeld, died on the 21 April 1924, 77 years old, in Schlitz, Hessen
he was married to Marie Mohr nee Mihm
I also found a marriage certificate for the same guy which reads.
Schlitz 10 August 1878
The barber Heinrich Mohr, born on the 9 June 1846 in Wetzlar
resident in Schlitz.
son of the deceased Johannes Mohr and Eisabetha Boländer
Married Marie Miehm, born 28 October 1860 in Schlitz
daughter of the deceased Christian Miehm and Katharina Döring
I have no idea if all this fits. It could be a lead
