I believe the answer is:

edith

'maybe she' is the definition.
I can't judge whether this defines the answer.

'tied the knot at southend?' is the wordplay.
'the knot' indicates anagramming the letters (I've seen 'knotted' mean this).
'at' is a charade indicator (letters next to each other).
'southend?' becomes 'h' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'tied' anagrammed gives 'edit'.
'edit'+'h'='EDITH'

Can you help me to learn more?

(Other definitions for edith that I've seen before include "Osbert's sister" , "Woman" , "- Cavell, nurse executed in 1915" , "and 19 Across: 'Little Sparrow'" , "Dame - Sitwell, English poet (Facade)" .)
