Their oldest son Richard Sackville of Buckhurst (1472 – July 18, 1524) was married in 1492 to Isabel Dyggs. Their oldest son Sir John Sackville of Buckhurst (1492 – October 5, 1557) was married to Margaret Boleyn. Margaret was a sister to Thomas Boleyn, 1st Earl of Wiltshire. His younger brother Richard Sackville had a less prominent marriage which resulted in the birth of Anne Sackville. Anne herself was later married to Henry Shelley.
Henry became father to a younger Henry Shelley. This younger Henry had at least three sons. The youngest of them Richard Shelley was later married to Joan Fuste, daughter of John Fuste from Ichingfield. Their grandson John Shelley of Fen Place was married himself to Helen Bysshe, daughter of Roger Bysshe. Their son Timothy Shelley of Fen Place (born c. 1700) married widow Johanna Plum from New York City. Timothy and Johanna were the great-grandparents of Percy.
Family
Percy was born to Sir Timothy Shelley (September 7, 1753 – April 24, 1844) and his wife Elizabeth Pilfold following their marriage in October, 1791. His father was son and heir to Sir Bysshe Shelley, 1st Baronet of Castle Goring (June 21, 1731 – January 6, 1815) by his wife Mary Catherine Michell (d. November 7, 1760). His mother was daughter of Charles Pilfold of Effingham. Through his paternal grandmother Percy was great-grandson to Reverend Theobald Michell of Horsham.
He was the eldest of seven children. His younger siblings were:
• John Shelley of Avington House (March 15, 1806 – November 11, 1866; married on March 24, 1827 Elizabeth Bowen (d. November 28, 1889)
• Mary Shelley
• Elizabeth Shelley (d. 1831)
• Hellen Shelley (d. May 10, 1885)
• Margaret Shelley (d. July 9, 1887)
Shelley's uncle, brother to his mother Elizabeth Pilfold, was Captain John Pilfold, a famous Naval Commander that served under Admiral Nelson during the Battle of Trafalgar.[8]
Descendants
Three children survived Shelley: Ianthe and Charles, his daughter and son percyby Harriet; and Percy Florence, his son by Mary. Charles suffered from tuberculosis but died in a rain storm as he was struck by lightning in 1826. Percy Florence, who eventually inherited the baronetcy in 1844, died without children. The only lineal descendants of the poet are therefore the children of Ianthe.
Ianthe Eliza Shelley was married in 1837 to Edward Jeffries Esdaile. The marriage resulted in the birth of two sons and a daughter. Ianthe died in 1876.
Shelley's son Percy Florence Shelley, and his wife Jane, adopted Jane's niece Bessie Florence Gibson. Bessie married Leopold James Yorke Campbell Scarlett, and so the Scarletts (later the Scarlett/Abingers after their son, Shelley Leopold Laurence Scarlett, succeeded his second cousin to become the fifth Baron Abinger in 1903) became heirs to the Shelleys. Several members of the Scarlett family were born at Percy Florence's seaside home 'Boscombe Manor', in Bournemouth. The 1891 census shows Lady Shelley living at Boscombe Manor with several great nephews.
