Sue,
Five children baptised at Wye, to William and Sarah Macey,
Mary 1818,
Samuel 1821, buried the same year aged 4 months,
Emily1822,
Amy 1828,
Ann 5 May 1831, buried 8 May as an infant.
Mother Sarah Macey buried (also) on 8 May 1831 aged 39.
Still no sign of a marriage locally.
Iwade is quite a long way from Wye. On the basis that William Macey and Sarah had a child Mary Ann baptised at Iwade on 12 October 1828, it seems pretty remote that the Iwade couple is yours, especially as Amy Macey was baptised on 25 January earlier that year at Wye.
William Macey buried 5 June 1852 from East Ashford Union House aged 72.
Maybe of some use.
All the best,
Tony
