I sort of thought that might be the answer, Valda, but thought I'd try anyway!

I did a free search on British Origins and, of course, it came up with quite a few finds for James Mitchell, but I don't really want to pay a subscription just for one look up. Don't suppose there's a free site?
Suffolk*sue, thanks for the suggestions about 2 of my missing marriages.
I knew about the first one - Sedbergh - and , to cut a very long story short, I've had a bit of a run around with it. You know the way it goes, one RO has this bit of info but if you want to know this, then you'll have to contact another RO. Turns out, the parish record entry in Sedbergh has Richard from Kendal and Jane from (I can't remember off hand but it was somewhere very near Kendal) - which is where my Richard & Jane had their family. Problem is, the marriage licence index (at another office!) had Jane marrying someone completely different!! When I queried this with the various offices, they had no answer!

As the marriage was a couple of years after the baptism of their first child in Kendal, it would perhaps have explained why they went off somewhere else to make it legal, but I really didn't know what more I could do to sort it out!

And that was supposed to be the short version!!

But the other suggestion for John Horwood and Martha is the right time - but it's a good 60 miles from where they had their family - in Wargrave, Berks. Still, it's the best possibility I've ever had so will investigate further. But...Smith!! Aghhhh!!
Thanks,
Jill
