John Sandys was appointed rector of Eversholt on 5 June 1766 and remained there until his death on 16 April 1810, according to CCED. He was, presumably [actually this is very dubious – EJW], the son of Samuel Sandys, first Baron Sandys, and Laetitia Tipping, who owned the advowson at the time. They acquired the advowson from the Earl of Orford some time between 1721, when the Earl appointed Pusey Hancock, and 1742, when the Sandys appointed Luke Morgan. They married on 9 June 1725. Laetita inherited Orford’s estate in 1727, which must have been very nice for her, and that would have included the advowson at Eversholt. Surprisingly, their full family tree isn’t in the obvious places online, and not even at this extensive family history site. Aha! Here is a more extensive tree, although its reliability is unknown. It does include a John Sandys, alleged to have died in Gernany.
