The Anderson Baronetcy, of St Ives in the County of Huntingdon, was created in the Baronetage of England on 3 January 1629 for John Anderson. The title became extinct on his death in 1630.[3][1]
His mother, Lady Anderson, was considered "a fair young rich widow", and had prominent suitors. She remarried after a few years, to the widowed courtier Francis Leigh.[4] Leigh was made a baronet under James I, and then in 1628 was created Baron Dunsmore, the unique new title in the Peerage of England of this period. Not having other court connections, Leigh owed the advancement to the influence of the Duke of Buckingham.[5] The letters patent for the barony included a special remainder, to his stepson John Anderson.[6]
