Between 1615 and 1618 Smythe and two cousins travelled abroad in the charge of Thomas Brett*. Returning as ‘a proper young gentleman of some 19 years old’, he was ‘inveigled and caught in affection’ with the daughter of the earl of Warwick, one of his father’s business rivals, marrying her in defiance of parental authority.
Shortly after Smythe entered into his inheritance, his wife’s uncle, the earl of Holland (Sir Henry Rich*), approached the royal favourite, the duke of Buckingham, to secure a parliamentary seat at Rochester for his kinsman.
Smythe left no trace on the records of the 1626 Parliament. In April 1627 he and his mother were criticized by the London charity commissioners for failing to convey various properties to the Skinners’ Company as required by his father’s will.
