Hi there! By his wife Rachel COOK, William GOLBY had just one daughter Ann who married 1796 at Stony Stratford, to Thomas GREEN. In 1773 at Wolverton, WG married his second wife Sarah GLEED, and they had Mary 1774, William 1775, James 1777, Elizabeth 1780 and Sarah 1782, all baptised at Stony Stratford. Mary, my husband's direct ancestor married 1795 James POPAY, a surgeon, and died at Calverton, Bucks, in 1848. Their children were Mary Gleed POPAY, Sarah Elizabeth POPAY (married Abraham BARRATT), and Lavinia POPAY.
I am thinking you must descend from Mary's brother William GOLBY who was a maltster of Stony Stratford? His will was proved 1841, and he names his wife Mary, son William, and daughters Sarah, Harriet and Ann.
William was a cousin of James Wake GOLBY who died 1842, and JWB was a son of a James GOLBY who died 1818, this James was therefore a brother of "our" William who married Rachel COOK and Sarah GLEED.......are you still with me?......SO, there were these brothers William GOLBY and James GOLBY, - James definitely of Banbury, Oxfordshire, and William certainly with links there (mentioned in Grafton Estate docs), and I think they had a sister Elizabeth who married a William LOVELL - but - who the parents of these were, I do not yet know!!
Will be most interested to hear if any of this is new to you, and if you might know anything further back.
