Hi Knellie,
Now I understand what you did. You checked the same time frame as I would have done given Ellen's pregnancy and the date of William's birth. This is turning out to be a much greater puzzle than I anticipated.
I am glad that you seem to be enjoying the experience
of searching for criminal records. I feel rather guilty about asking someone to do all this work.
It might be fun to find a black sheep of your own

.
I have one, but he never got caught and lived out his life
in comfort, hiding on a Carribean island. It took me a couple of years to track him down, great fun.
Cheers,
Carmela
