Sir Philip Parker-a-Morley-Long, 3rd Baronet

Sir Philip Parker-a-Morley-Long, 3rd Baronet (1682 – 20 January 1741) was an English politician.

Born at Arwarton, Suffolk, the son of Sir Philip Parker, 2nd Baronet, and Mary Fortrey, he took the name of Long on inheriting the estate of Whaddon in Wiltshire from his great-uncle Sir Walter Long. The original Coat of Long was, through some error, allowed to him by the College of Arms.

He served as Member of Parliament (MP) for Harwich 1715–1734.

On 11 July 1715 he married in London, Martha East and they had four daughters:

• Martha (1716–1775) married John Thynne Howe, 2nd Baron Chedworth
• Elizabeth (1717–1757)
• Katherine (b. 1719)
• Dyonisia (b. 1722)

On 20 January 1741, John Perceval, 1st Earl of Egmont wrote in his diary:

"This morning died my brother-in-law Sir Philip Parker, at 3 o'clock, choked by one of those fits he has had for 12 weeks past at sundry times."
