There seems to be some doubt about Peter Hickson, Snr. I have both records: Peter Hickson, born 1812, son of James Hickson & Cicely Ambrose. This Peter was baptised 20 November 1812 in St Nicholas, Liverpool. He had 2 siblings, Thomas born 1810 and Elizabeth, born 1814 and Peter Hickson, who, according to the IGI, was born 15 December 1813 in Bolton le Moors to Benjamin Hickson and Alice Holme.
Can you give me the source for the date of birth of Peter Hickson, Snr. and the source for the birth of his son, Peter, in order to try and clarify this.
