By the reign of Henry III Horsey’s ancestors owned the Somerset manor from which they took their name. They acquired Clifton Maybank by marriage around two centuries later, and first represented Dorset in Parliament in 1421. Horsey’s father, Sir Ralph, owned more than 11,000 acres in these two counties, but his extravagant lifestyle ran him into debt, and he began selling land in 1597.
Horsey first entered the Commons as a Dorchester Member in 1614. The only non-resident to sit for the borough in this period, he was possibly nominated by Freke, who had himself been returned there in 1586. One of the many novices in the Addled Parliament, he left no trace on its records.
Presumably in the hope of improving his financial position, Horsey acted as agent for the 1st earl of Cork in 1623 when the latter purchased some Irish estates recently acquired by lord treasurer Middlesex (Sir Lionel Cranfield*) from Bevill Grenville* and his father.
At the start of the next reign Horsey’s local standing may have suffered through association with the disgraced earl of Bristol (Sir John Digby*), as another of the trustees for his estate was Philip Digby*, the earl’s brother. However, this was a minor concern compared with his rapidly worsening debt crisis. By 1629 even his father-in-law had lost patience with Horsey’s ‘expensive courses’ and reluctance to fulfil his financial obligations, and sued him in Chancery.
Horsey was under royal protection from his creditors throughout 1631, and in the next few years he sold or mortgaged almost his entire estate, even parting with Clifton Maybank in 1634 for £28,000.
