Unfortunately the parish register for Ridley, Surrey around the time of Elizabeth's birth is riddled with errors and omissions, and the birth record of Elizabeth Pantlin appears to be affected by this. There were around 1760 two Pantlin families having babies. John (son of John Pantlin and his wife Ann) and his wife Ann née Standen/Stanton had had a son Robert in 1757, and another son William in 1759. John's younger brother Robert and his wife Sarah née Pullen had a son James who was baptised 12 October 1760. Then in 1761 the register records two more Pantiln baptisms: 27 Sep 1761 Elizabeth and 11 Oct 1761 Ann. These 'both' appear to be attributed to John and Sarah Pantlin (although the latter actually reads 'Sarad' for the mother's name). It is impossible for the same parents to have two daughters born two weeks apart, and further there is no evidence for any other John Pantlin in the parish other than the husband of Ann and his father (who was around 60 at the time). It appears that the vicar or clerk who made the entries in the register simply got the two families muddled. One of the daughters was born to John and Ann and the other born to Robert and Sarah -- but which is which?
I would very much welcome any suggestions about how to untangle this.
