My husband's g.grandmother stated she was 18 when she married in 1867 when, in fact she was only 15. Her husband stated he was 22 which was correct. I don't know where her father was I can't trace him after 1857 in a Trade Directory, but her mother was still alive, she didn't die until the following year. As she got married at Manchester Cathedral, maybe she married without her mother knowing. In any case the marriage lasted for 35 years before she died of cancer of the uterus, her age was correct on her death certificate, so obviously her husband knew her real age.
