You asked about the marriage of David Ayling in Alton. Although he and Elizabeth were said to both be ‘of this parish’ in 1770, David does not seem to have been baptised there. Presumably he was just working there at that time. The Petersfield connection could be because of the settlement certificate but that shows that the family were from Alton and they do not seem to have stayed there long. Yours Jane
1770 24 Sep., David Ayling married Elizabeth Winkworth at Alton by banns. Both were said to be ‘of this parish’. Witnesses were Thomas and Ann Swain.
1771 probable baptism of Sarah Ayling, daughter of David and Elizabeth but there are lots of missing entries from the Alton registers at this time.
1774 James Ayling, son of David and Elizabeth, baptised at Alton. (Reg)
1777 8 Apr., Jesse Ayling buried at Petersfield.
1779 settlement certificate among the Petersfield Parish records for David Ailing, turner, his wife Elizabeth and children Sarah aged 8 and Jane [sic] aged 5 of Alton. (108M70/PO12) Presumably James was misheard as Jane.
1782 11 Oct., George, son of David and Elizabeth Ayling, baptised at Alton. (Reg) The family had returned (or had been returned) to Alton.
Son James married and their first children baptised were:-
1798 Martha

Daughter Sarah may have married in 1790 - William Butler.
1828 24 Jan., Elizabeth Ayling buried in Alton, aged 82.
1828 12 Aug., Daviid Ayling buried in Alton. Said to be aged 78.
[This suggests that he was born in 1750 but that would have made him underage when he married and that does not appear to have been the case so he was probably born pre-1750.]
1828 6 June, Mary Ayling buried aged 45
1829 1 Mar., Mary Ayling buried aged 53.
1831 4 July, George buried aged 48.

No Jesse appears to have been baptised c1808 in Alton but he could have been christened James?
