Hello and thank you to both of you!!

What I'm trying to do with this information is to confirm (as far as is possible) that I have the right family for Ann Bradford.
There are two possibilities I think, though it's so confusing, all these villages were so close together. If she was born in Westley Waterless or Burrough Green, would she be otp when she marries in Woodditton? I know they were all close.
The two possibilities are :
Ann Bradford c. 9 September 1806 Westley Waterless father Richard mother Letitia. This is the family I believe it is, because in all the census from 1851-71 she states her place of birth as Westley, Cambs.
But the witness at the marrige, William, has made me doubt ... as the other option is :
Ann Bradford b.3 Oct 1806 Burrough Green father William mother Mary.
I do know however, that The first Ann had a brother named William, b. 1804 in Westley, so equally this could be her brother as witness.
I expect as so often, I can never know for sure. But does it seem reasonable to go with the first family? Any opinions / help appreciated as always
