I had come to the same conclusion re Sarah Green and Edward Welling but wasn't sure how Sarah Green ended up marrying in Churcham if she was born in Hartpury. I haven't found a baptism record for Sarah born about 1803 which was my original enquiry last year.

Sarah goes on to have a daughter Keziah in 1833 and this Keziah marries Samuel Poyner in 1864 in Huntley. Before her marriage Keziah has a son James Llewellyn and he is my great grandfather.

So is it possible the other Keziah born about 1811 / 1812 is the sister of Sarah born to Edward and Sarah? And why is the only evidence of her marriage to Thomas Partridge on the Familysearch website?
