Hi Jean
It's a while since I went to Preston as I'm up in Cumbria and I've not had chance for a few years, but if someone is going, oit doesn't take long to look. I
was given a huge tome, with a two page or so, beautifully written entry for each officer. I think it was in alphabetical order. Someone might go in. It's great to get the copy eventually, but at leastt if you have the info you can use it.
I'll look for the exact details later, but it gave his army regiment and dates and I was lucky it was on the National archives and I requested a scan, got an estimate by email and ordered the army record online. It came in abiout a week, for a few pounds, beautifully oresented, A3.
Your ancestor may not have been in the army, but loads were.
It's worth a look on The National Archives UK search. I didn't play with variants, but if you look, there's a Set of notes for a police Constable Stwad of Tong - only a couple of years, early 19C, at West Yorkshire Archives, in Bradford. If you fpress the right links you should get the email address.
If he was ever in Wigan, I found two stories about him in newspapers on the Wigan world site.
I'll look for the exact details later, when I've more time to play.
Best wishes
Emms
