Hi Liz,
It is very kind of you to look for her in the MM records - many thanks - but she is a bit of a mystery woman so I don't think her parents can be found there if they can't be found online. She gave her birthplace as Ramsey in all censuses where she can be found, but isn't in the IGI under Ramsey extracted records (nor in Maughold).
Then her burial seems to be in 1871 - after the census - and her husband John Wade and family are still in Ramsey, but she isn't with them.
I think she has to go in the too-hard basket!
Sue
