I've just looked at the marriage entry on A******y and Catherine states her father is deceased.
I have her father David as dying on 24 Jul 1901 at 33 Parrys Entry, Foregate Street, Chester.
How did you connect this Catherine to brother Patrick and siblings in Chester?
I'm not convinced this is the same girl

as 'Kate' is in Chester on the 1901 census and is single.
I think your Kate was born in Bermondsey abt 1872 with parents of the same name i.e. David & Mary.
Siblings were Richard and Margaret per the 1881 census.
