Williams, alias Williams Onslow of Spettisbury
The Williams family of Spettisbury in Dorset previously owned Tendring Hall in Suffolk. They were a branch of the Williams family of Wollaston in Shropshire. Here is the information I have on them :
● William ap David was father of
● Reynold Williams of Wollaston in Shropshire. Sheriff of Montgomery. He married Margaret said to be daughter and heir of Fulk Lee and had a son
● Thomas Williams of Wollaston in Shropshire. Sheriff of Montgomery. He married Blanche daughter of Robert Powell and had issue
1. Reynold, of whom presently, and
1. Rose, who married by 1551 (as his 1st wife) George Evelyn (who died 30th May 1603). Their eldest son Thomas Evelyn (1551-1617) was grandfather of Sir Edward Evelyn (1626-92), 1st Baronet of Long Ditton in Surrey.
The son,
● Reynold Williams of Wollaston in Shropshire, was Sheriff of Montgomery. He married Margaret daughter of Gerard Gore (c 1516-1607), Alderman of London, by his wife Helen (d 1608) daughter of Ralph Davenant of Davenants Land in Essex. Margaret was a sister of John Gore Lord Mayor of London 1624-5 and of Sir Paul Gore 1st Baronet of Manor Gore in Co.Donegal. Reynold and Margaret had, with other issue,
1. Thomas of Wollaston in Shropshire. Eldest son and heir. He died in 1624.
6. Edward, their 6th son of whom we treat.
● Edward Williams became a Merchant of London. He married Mary daughter of Robert Palmer of Hill in Bedfordshire and left a son,
● Reynold Williams of Stoke by Nayland in Suffolk. His will was proved on 3rd May 1689. He married 1stly Mary daughter of Richard Peacock but she appears to have left no issue. He married 2ndly Sarah daughter of Thomas Dyke of Horsham in Sussex. By her he had issue
1. Thomas Williams, eldest son and heir, was of Tendring Hall near Stoke-by-Nayland in Suffolk. He married Elizabeth (baptized at Kedington in Suffolk on 30th May 1659), 4th daughter of Sir THOMAS BARNARDISTON 1st Baronet of Kedington in Suffolk by his wife ANNE, younger daughter of Sir WILLIAM ARMINE, 1st Baronet of Osgodby in Lincolnshire. Thomas Williams will was proved on 30th May 1718. He left issue
i. Thomas Williams, only son and heir, was of Tendring Hall. He married Alice daughter of Anthony Bramston of Skreens in Essex by his wife Katherine daughter and co-heir of Sir Thomas Nutt. Thomas is said to have either died without male issue, or may even have died childless. The Tendring Hall estate then passed to his uncle John, as noted below.
i. Anne, who married (as his 3rd wife c 1732/3) Sir ANTHONY THOMAS ABDY, 3rd Baronet of Felix Hall in Essex. Sir Anthony was baptized at Kelvedon in Essex on 5th October 1688 and died on 11th June 1733 leaving two daughters and co-heirs by his 2nd wife (the elder of whom married Anne's cousin Richard Williams). Anne has been described by some as the Heiress of Tendring Hall. However this is unlikely as the estate was in the hands of her uncle John by the time he died in 1741. She died childless on 21st September 1745.
2. John, Lord Mayor of London, of whom presently.
3. Edward, whose only surviving child, Sarah, died unmarried.
