Hi Genie,
I've had another look at the BT's for Middleton in Teesdale and think this must be Tamer's baptism. (image 191)
Tamer Walton born Nov 28th 1808, bapt 2nd April 1809, daur of Miles Walton of Middleton, Miner, by his wife Mary Collinson both native of this parish of Middleton.
This was followed soon after by a burial - Tamer Walton wife of Miles Walton of Middleton, Miner, died 21 May 1809 buried 23rd May 1809 aged 43 years
However, it pays not to jump to conclusions because I then found another baptism - Mary Walton born 16th Dec 1810 bapt 13th Jan 1811, 2nd daur of Miles Walton of Middleton, Miner, by his wife Polly Collinson, both native of this parish
If these are your Tamer's family then you know her parents' names and where they were born, and that mum Mary was also known as Polly. And there's a good chance that the burial was of her grandmother so that's a further generation.
Regards
Colin
