[3] In the 1550s the monastic property that became St Alban's Court, at Nonington, was bought by Thomas Hammond.
He had a supervisory role, in drainage work started from 1649 by Sir Miles Sandys, 2nd Baronet (died 1654) and others, under Cornelius Vermuyden, and was paid £20 per month.
[15][16] The second son, Anthony Hammond, bought Somersham Place, a former episcopal palace of the bishops of Ely, around 1660; or leased a wing of what was a building falling to ruins.
[16] He speculates at one point in a letter from Paris on taking a higher degree at Oxford, through John Wilkins; and mentions that his scientific library had been built around suggestions from Lawrence Rooke, Charles Scarburgh, Seth Ward and Christopher Wren.
[1] He had practical support, and an introduction to Sir Kenelm Digby, from Henry Holden in Paris, Holden being a good friend of Lady Mary Stanley, mother of Thomas Stanley and sister of Anthony Hammond, William's father.
He carried out some research on French silk manufacturing, at the request of Edward Digges, his mother's brother.
[27][28] Sir Edmund's heir Anthony Bowyer, a future barrister and politician, matriculated at Christ Church, Oxford in 1651.
[29][30] Boywer fell ill with smallpox at Nîmes, and Hammond tended him there in September and October 1657.
[35] Marsham's wife Elizabeth was a sister of Anthony Hammond, his father, so this was a marriage of first cousins.
[36] The children of this marriage were three sons, one of whom died young, and two daughters: their daughter Anne married William Wotton, and Elizabeth married Oliver St John, son of Sir Oliver St John (died 1673), the judge.
The suggestion that William Hammond FRS, of Kent, had travelled abroad as education for a future physician occurred in the 1792 Topographical Miscellanies of Samuel Egerton Brydges.
One set, which passed through the hands of Bruce Ingram, is in the Brotherton Collection of the University of Leeds.
