Yes those Mary Browns are all feasible ...I wonder how many possibilities there are
I havent looked for Mary in 1841 as I didn't have a surname ...will do that now

Just had a thought, Kirkpatrick Juxta is not that far from Gretna Green could Nimrod and Mary have married there?
I think Gretna records are An****ry but I have'nt got subscription.
I couldn't find a marriage in Gretna Green for them
If the marriage took place I would assume we are looking after 1841 census when Nimrod was in Northampton and the birth of their dau Sarah born 1850 Frodsham in Cheshire (Sept qtr.)
Lots of Mary Brown's marrying 1846 - 1851 Cheshire BMD but no one named Nimrod

I could only find the Sept. 1842 marriage entry in Daventry (Northamptonshire) between 1841-1850

Nimrod Gardner
To either
Hannah Dobbs
Ann Hollis
Letitia Waite
Other males
William Reynold
William Walton
Nimrod age 20 cordwainer on his own in 1841 living Rushton Northampton
might be worth looking to see if there’s a Mary Brown anywhere close by
then by 1851 he’s with his wife Mary born c 1830 Scotland (pob Moffat 1881) and child
Sarah 6mths born Frodsham Cheshire c1850 living registration district of Runcorn
Was Mary living in Scotland, Northampton or Cheshire 1841?
There is a Mary Brown age 12 living in Runcorn but her pob is indicated by ‘Y’ she is with
Samuel Brown & Margaret? and 5 older siblings
