Lydiard Park, Swindon Earl Tylney and his wife Dorothy Glynne had seven children: • Emma (1707-1758), twin. Married
Sir Robert Long, 6th Baronet (d. 1767), of Draycot, Wiltshire. • Elizabeth (1707-1710), twin. • Frederick (1709-1715) • Richard (1711-1734), predeceased his father. • John (1712-1784), 2nd Earl Tylney (see below). • Dorothy (1717-1786), unmarried. • Josiah (1718-1760), a Lieutenant or Captain in the Royal Navy, likely to be the officer depicted by Nollekens seated dressed in a blue coat. He seems never to have changed his surname to "Tylney". He married Mrs Henrietta Wymondsold (1729–1763), divorced wife of Charles Wymondsold of
Lockinge, Berkshire, only daughter of
Robert Knight, 1st Earl of Catherlough. They had a son, Josiah, born shortly before their marriage, who was brought up by his uncle, but died in Florence on 5 July 1774, aged 20. Both Josiah and Henrietta had their portraits painted by
Francis Cotes, which are now in the collection of
Lydiard Park, Swindon. On the Earl's death in March 1750, he was succeeded by his eldest surviving son
John, who had also adopted the surname Tylney, by private act of Parliament, the
Younger Sons of the Duke of Rutland's Names Act 1734 (
8 Geo. 2. c.
2 ) after his elder brother Richard's death in 1734. John therefore became the 2nd
Earl Tylney. The 2nd Earl was MP (2nd Member) for
Malmesbury, Wiltshire (1761–1768), possibly as a result of his family connection with the locally influential Long family, and a
Fellow of the Royal Society (1746). On his death in 1784, unmarried, the family titles all became extinct. His heir was Sir James Long, 7th. Baronet, son of his eldest sister Emma and her husband
Sir Robert Long, 6th Baronet (died 1767), of
Draycot, Wiltshire. The 7th Baronet was required by his inheritance to adopt the name Tylney-Long, which he duly did, becoming
Sir James Tylney-Long, 7th Baronet. ==References==
