The Simeons appear as yeoman tenants of the Pyrton estate of the dean and chapter of Windsor, six-and-a-half miles from Wallingford, in the early sixteenth century.
In 1614 Simeon was returned for Wallingford, almost certainly on the interest of his mother’s uncle (Sir) Michael Molyns†, whose electoral interest was acknowledged in that year by the borough’s high steward, William, Lord Knollys (William Knollys†).
In 1625 Simeon was pricked sheriff of Oxfordshire, the only office to which he was ever appointed, but he was spared the expensive duty by the intercession of the 1st earl of Montgomery (Sir Philip Herbert*).
Simeon took no apparent part in the Civil War, retreating at one stage to Sussex.
