There do not appear to be any baptisms of a Sarah Knight in Tanworth at the relevant time. The most likely baptisms are:

Year     Place                    Parents

1698     Rowington           Joseph & Elizabeth
1710     Claverdon            Thomas & Ann
1714     Claverdon            Robert & Elizabeth   (1715 on the modern calendar)

I have found several family trees which have gone with the 1714/15 baptism but not found how this was justified.
