Possible John Pickerings:

1) bp 1755, f:John, Hull St.Mary Lowgate
2) bp 1760, f:Richard, Hedon (Hull)
3) bp 1764-6, f:John, Kirk Ella (Hull)
4) bp 1775, f:Thomas, Hull, Holy Trinity

All are in Hull so all possible from that standpoint.

1755 John seems unlikely as the age puts him at 44 when married and 47 at dau.’s birth.
1760 John also seems unlikely as his age is still a bit high, 39 at marriage, 42 at dau.’s birth
1764-6 John is getting better with an age of 33-35 at marriage and 36-38 at dau.’s birth, still seems high
1775 John seems like the favorite as he would be 24 at marriage and 27 at dau.’s birth. This seems a good match to a wife who would likely be 19 at marriage and 22 at birth (assuming the 1780 Sarah Spencer)
