From the 13th century onwards, if not before, members of the Frowyk family were prominent as London merchants and Middlesex landowners. With a father and grandfather who had both represented the county in Parliament, it was inevitable that Thomas Frowyk would be called upon to play his part in local government, although he clearly lacked the driving ambition which made his younger brother, Henry, such an important figure in the City.
Frowyk appears to have been fairly inactive until May 1418, when he was appointed to his first royal commission. His close connexion with (Sir) Thomas Charlton, the son of his mother’s second marriage, was already well established, however, and the two men remained on intimate terms for the rest of their lives, sitting together for Middlesex in the Parliaments of 1422 and 1427, as well as becoming involved in each other’s property transactions. Frowyk was often made a feoffee-to-uses by his brother, Henry, who invested a substantial proportion of his commercial profits in land: both of them also acted in the same capacity—many times with their half-brother, Charlton—for friends and neighbours, including William Waldern, John Durham and Richard, Lord Strange.
Frowyk’s career followed a conventional pattern: he sat for over 30 years on the Middlesex bench, and served on a creditable, if not unduly impressive, number of local commissions. Five times a shire knight for his county, and a regular attender at the Middlesex parliamentary elections (he was present on at least ten occasions between 1420 and 1442 to see others returned to the Commons), he was, none the less, a man of somewhat circumscribed political interests.
Despite his reputation as a moderate, peace-loving man, Frowyk was prepared to come to the assistance of his half-brother, Sir Thomas Charlton, who, in 1438, became involved in a dispute with Ralph, Lord Cromwell, over the enclosure of common land in the manor of Edmonton. In August of that year Frowyk and his neighbours assembled there in force to defend the rights which had been lost, but which, thanks to Cromwell’s conciliatory behaviour, they were soon able to regain. Frowyk was probably quite old by October 1439, the date of his first will, although he lived on for another ten years, during which he endowed a chantry chapel at the church of South Mimms with property from his estates.
