James & Margaret had a number of children baptised at Castle Hedingham : St Nicholas : Parish Register
ANN 1747, Sarah 1748, Hannah 1750 (buried 1851), JAMES 1752, WILLIAM 1757, REBEKAH 1759, MARY 1761, ALICE 1863, plus below.
Mehetabel (FEMALE) 1754, (Hannah Jemima 1756 The child's name was originally written Hannah but this was underlined and Jemima written above and slightly to the right; it's unclear which is correct or whether two names were intended. She was buried later same year)
John & Sarah had children baptised there from 1761, maybe related.
Based on the parents names the James birth 1722 posted by Girl Guide looks very possible.
