I have checked the 1851 and 61 Wrenthorpe for Mary
without success. Some Mary Aveyards in the surrounding
areas but they do not quite fit. Don't give up, a fellow on
the Derbyshire board found me a hit that I missed when a
number of Naylor families were indexed as Maylor, I searched
for every configuration of the last 4 letters but never changed
the first. to complicate things the forename Elijah was indexed
Elizah
Some points must be proved by certificates, the marriage cert
would give you Marys father.
Until a full 1841 index is available it is difficult to find where
Marys parents are.
The next step would be a visit to Wakefield Archives, book
before you go, the staff are very helpful. Outline exactly what
you require e.g. Parish Records for Wrenthorpe. When you book
the registers or indexes would be ready for your visit.
Another point of call would be Wakefield Family History Society.
See their Web Page, they do look ups for a fee and have lots of data.
When you post your requests here, it would be better to type
details than provide difficult to read links, you have done the work
finding them, make it easy for us. Good Luck in your search, you are
getting there.
The statement above is my point of view take your directions from
the moderators of the board.
