Here is your previous thread re the Warners
https://www.rootschat.com/forum/index.php?topic=795130.0I am glad I have seen it as I was going to post some of the information already posted.
The children all have mmn Smith and I would have thought that if the maiden name was Worth, then that would have shown.
I was going to ask about Mary A’s marriage to Nathaniel but have found one in 1866 is that it? It is Carshalton and Mary Ann Smith’s father is shown as Samuel Worth.
There is this marriage in 1840 but close to 1841 where you have Nathaniel and Mary A together in Sussex

18th September 1840 St Mary’s Newington.
Robert Smith Widower Gardener Peckham, Father John Smith Gardener
Elizabeth Mary Worth spinster Peckham, Father Samuel Worth deceased.
