but I dont seem to be able to find Susannah's baptism.
Hi
Perhaps a bit earlier than you expected, but I don't see another at present..
Camb FHS Bap Index has 1657 Coton
And the FHS PR transcription has this:
Doesn't give a date for the bap., just the year 1657.
Moulton Susanna, d/o William & Elezeabeth, born 15 March 1657.
If it helps there looks to be a sibling, William, born 14 Jan 1659.
