Looking at the birth of their children and the time span between the births.

It seems a long time between the birth of William and Winifred. I mean couples usually have a few children in succession at the start of their marriage and then it tails off later.
I wonder if they had William and went to Cardiff to register him as down there no one would know that they weren't married and married in the years between William and Winifred.
There is this possibility:-
