Curate with a hearing problem?

There seems to be a bit of a trend about oral traditions/hearing issues here at the moment.

My WorldConnect database LornaHenderson has been republished to include the last few months worth of updates.
Many updates are the result of checking off research from the early days when so few sources were readily available - in particular some of the dates for the family of Anna Maria ANDREWS  and John Lidderdale PURDIE (having been prompted by a DNA match with a descendant), but also some of the BAINs.
The most recent set however were for the family of Richard MATTERS/METTERS and Elizabeth NORRISH thanks to a smartmatch from MyHeritage alerting me to a tree posted by a descendant.
From Devon to London to Argentina to Devon to New Zealand.
I've found a 5th cousin lives over the hill from me!
This exercise reminded me that I'd never satisfactorily resolved/tidied up the family of Ann daughter of Richard and Elizabeth, nor found the baptisms for the family.
The latter turned out to be because back when that research was first done, Non Conformist baptisms weren't as readily available. Now they are indexed on FamilySearch and Ancestry (at least), with the images available on TheGenealogist.co.uk
That solved I turned my attention back to Ann's marriage to John BORROWMAN.
Still no joy.
Has anyone found it?
The best I could come up with was John's marriage in 1848 to a Mary Ann MEADOWS.
Right father and father's occupation, date fits known info, ie Ann shown in the 1851 census where she was living at home with her parents, shown as Ann BORROWMAN, married, and Richard/Elizabeth's granddaughter Fanny Barford MATTERS aged 3 born Devonport in the household.
The first  child for Ann and John I know about is son John born 1853.
Fanny later shows up with John and Ann as daughter, Fanny BORROWMAN, but her marriage certificate to George BURDICK shows her father as _____ and herself as Fanny BORROWMAN nee MATTERS, spinster

So, can anyone claim a Mary Ann MEADOWS of full age, X her mark, father Richard MEADOWS, farmer, who married John BORROWMAN, carpenter Royal Navy residence at marriage HMS Wellesley?
Is this Ann MATTERS as recorded by a Curate unused to the local accent? But if so, why Mary Ann?
