Welcome to Rootschat
His second marriage was 1952 so any children born to that marriage could still be living.
Rootschat has a strict no living persons policy to protect peoples privacy so we would not be able to provide any details
Here's some general guidance for finding the information
There is a tree on Ancestry if you have a subscription which has some info. If not - most local libraries have free access. He was b 1922 - died 1998. Does not appear to have left a will.
www.freebmd.org.uk - the marriage can be found in the March qtr 1952
Use that info to search for births with that combination of surname & mothers maiden name on both freebmd or the GRO index on Ancestry. 2 possibilities in the same registration district as the marriage
However - If his second wife was previously married - any births will show her birth surname & not the surname she married under. You may need to buy a copy of the 1952 marriage cert to get that information
