Spencer Baronets

There have been three baronetcies, all in the Baronetage of England, created for members of the Spencer family, both for descendants of two younger sons of Sir John Spencer (1524–1586) of Althorp, Northamptonshire:

The Baronetcy of Spencer of Yarnton was created on 29 June 1611 in the Baronetage of England for Thomas Spencer, Member of Parliament for 1604–11, son of Sir William Spencer of Yarnton, Oxfordshire, the third son of Sir John Spencer, Kt. of Althorp. The third Baronet also represented Woodstock 1660–1679. The baronetcy was extinct on the death of the seventh Baronet as a minor in 1741.

The Baronetcy of Spencer of Offley was created on 14 March 1627 for John Spencer of Offley Place, Great Offley, Hertfordshire, the son of Sir Richard Spencer, the fourth son of Sir John Spencer, Kt. of Althorp. His sister Alice, who married Sir John Jennings of Sandridge, had 22 children, and was the grandmother of Sarah, 1st Duchess of Marlborough and of her cousin and political rival Abigail Masham. He died without male issue in 1633 and the Baronetcy was extinct, but was recreated on 26 September 1642 for his brother and heir Brocket Spencer. The fourth Baronet was Member of Parliament for Hertfordshire 1705–08. On his death the Baronetcy was extinct. His estate was inherited by his four daughters, and ultimately by his greatgranddaughter who married Sir Thomas Salusbury
