Hi Calmar,
Many thanks for looking that out, but I already have that information, maybe I should have said. I have his death and marriage, and I've found him in censuses 1911, 1901, 1891. I've also visited the cemetery.
The ages don't tally up exactly, giving his birth between 1865 - 67. Unfortunately, even though I have his father's name from his MCert (John Comer) there are no unique Michaels within the date range, and a couple of possibilities if I go to 1864 or 1869, or further. So I'd like to get some kind of fact that would make it clearer.
Best wishes
Steve
