Hi, There is no Sarah Bax in Birchington records, the closest in this area is Sarah Browning Bax christened at Monkton 23/06/1793 the base born daughter of Mary, but I have found the following on the IGI the dates are a bit out but that sometimes happens on the IGI. Sarah Bax christened 30/12/1787 at St Laurence Thanet daughter of Stephen and Sarah Bax Sarah Bax born 1790 married George Hewitt about 1812 Ramsgate Kent. Could be her as they had a habit of calling there sons after the grandfathers. Hope this helps, Regards Joan.
