Sir Oswald Mosley, 1st Baronet

There have been three baronetcies created for members of the Mosley family, one in the Baronetage of England and two in the Baronetage of Great Britain. Only one creation is extant. Since 1966, the title has been held jointly with Baron Ravensdale in the Peerage of the United Kingdom.

The first Mosley Baronetcy, of Rolleston in the County of Stafford, was created in the Baronetage of England on 10 July 1640 for Edward Mosley, of Rolleston Hall, a grandson of Sir Nicholas Mosley of Hough End Hall (who acquired the Manor of Manchester in 1596 and was Lord Mayor of London in 1599) and nephew of the lawyer Sir Edward Mosley (the youngest son of Sir Nicholas and his first wife Marjorie, née Whitbroke). Sir Edward was a lawyer who had been knighted by King James I in 1614; appointed a justice of the peace and Attorney-General for the Duchy of Lancaster; and elected as a Member of Parliament for Preston in 1614, 1620-2, and 1624-5. It was Sir Edward who first acquired the properties of Rolleston Hall and Rolleston on Dove that became the family seat. Sir Edward (1596-1638) died unmarried and without issue, and his estates were inherited by his nephew—the Edward Mosley who was to become the 1st Baronet.

The 1st Baronet's father was Rowland Mosley (1558-1616), another son of the aforesaid Sir Nicholas and his wife Marjorie.

The second Baronet, also called Edward, sat as Member of Parliament for St Michaels. The baronetcy became extinct on his death in 1665.

The second Mosley Baronetcy, of Rolleston in the County of Stafford, was created in the Baronetage of Great Britain on 18 June 1720 for Oswald Mosley, a third cousin of the second Baronet of the 1640 creation. The title became extinct on the death of the third Baronet in 1779.
