This is his son: John Horwell

What about his father's details from the marriage cert? (or was the date a transcription?!)

oops - you're right Merry

His father's name was John Horrell on the marriage cert.

I do have some info about people that may be his parents but I don't want to put it up because I think it's not 'solid' enough. "a very reputable researcher told me, so it must be true" is what my contact said.

I contacted this very reputable researcher who told me why he thought it to be true but I'm still not convinced....

Does it give his father's occupation on the marriage cert? And what were the witnesses' names?

Father's occupation 'labourer'................lol! not too helpful is it? Especially with all the name variations and the moving from Crediton to South Devon too.

Witnesses: John Adams & Susan Beard..... I have no idea who they are

A John Adams married a Grace Horrel 15 Jul 1804 at Cheriton Fitzpaine, Devon, but it's probably just a coincidence. Unless Grace Horrel is in your contact's tree!

Thanks Kate, I'll look into that.

The 'reputable researcher' has based all his research around Newton St Cyres & Upton Pyne.... (PR's that are online).

Grrrrr.....
I've just checked the IGI for Shobrooke:
There are birth records for the Horrell(+variants) name between 1750 & 1781 (4 sets of parents).
and marriage records 1751-1804 but the male Horrell marriages are 1751, 1761, 1782, & 1787.

It's all too early for my chap born in 1816. :(:(

I went through the registers in Devon Records Office too a couple of years ago - :(
