Robert TALBOT buried 9 February 1837 aged 57yrs [1780] in Clifton Hampton
Ruth TALBOT buried 25 May 1847 aged 66yrs [1781] in Clifton Hampton
Lyn.
If I may hazard a guess....
A Ruth FRUIN was baptised at Cowley in 1780 to John and Elizabeth {see IGI}
John FREWIN from Mongwell married a Elizabeth BRUCH in Brightwell Baldwin in 1760 {see IGI}.
They may of gone to Cowley after their marriage as there's no baptisms in either Mongewell or Brightwell by the looks of it and a John/Elizabeth started baptising in Cowley by 1763.
A John Frewin was baptised in Ipsden 1736 and 1739 {see IGI}. A burial with an age would help here.
A lot of FREWINs in Toot Baldon too. Even a Ruth FRUIN but too young at the time.

Like a said a guess...it needs a lot of chasing up to confirm things...
