Gee, you have been busy on my account!Thanks for all of this.
Yes I've had a look at the FreeBMD site, which is how I confirmed Matilda's maiden name.
'Fraid that the Martha option you found isn't the one sought as she is too old.Mitchell was born around 1849 and firstly married in 1869, so for Martha to be 69 in 1872 means she was born in 1803, and old enough to be Mitchell's mother or an aunt or even a very young grandmother.
Mitchell's and Martha's or Susannah's daughter, Alice, was born circa 1870, so Mitchell's wife probably died in childbirth or soon after.I do know of re-marriages of widowers within a year of the first wife's death, but they are rare.
I need to get hold of the Census of 1871 to see when Martha or Susannah were known to be living or dead, then go back to the GRO indexes.
I haven't done much GRO index research into Waddingtons outside of Bradford, so the extracts I have for that time don't include the Keighley-based family members.
Where do your Waddingtons come from, Ken?I'll check my database and see if I have any possible connections to them amongst my Australian resident people.
