Hi susyswan,
On the IGI there is an extracted entry for;
Sarah PURDUE, born 11-7-1812, Bapt. 26-11-1812 d/o John & Sarah, in the
Ebenezer Weslayan Ch. Hungerford, Berks. This parish is not too far away from Newbury.
The alternative would be to post a request on the Oxfordshire board to see if anyone has the
PRs for Kidlington which may indicate when she married in 1833, where Sarah came from.
