According to Chamberlain, Smythe’s knighthood in 1617 was a precondition of his marriage to Mary Franklin, who brought him a substantial dowry of £4,000. The union was possibly not childless as is usually supposed, for the financial records of Mary’s brother, Sir John Franklin*, include payments during the mid-1620s for the education of a boy named John Smith.
Returned for Mitchell to the first and second Caroline Parliaments, Smythe probably owed his seats to the influence of his cousin, Sir Richard Buller*, who belonged to the same Cornish gentry faction as John Arundell*, the borough’s principal patron. Smythe left no trace on the records of either session.
