Armyne was created a baronet in his father’s lifetime, and a fortnight later married the daughter of Sir Michael Hicks. He was returned at a by-election for Boston in 1621; the corporation chose him, possibly without his knowledge, ahead of two external candidates, and admitted him to the freedom of the borough gratis, ‘in regard he is a gentleman of note in this country and likely to do good service to this house without anyways charging them’.
In 1625 Armyne was returned for Grantham, but again went unnoticed in the parliamentary records. The following year he was elected for Lincolnshire, presumably with the support of the 4th earl of Lincoln. He was appointed to eight bill committees during the second Caroline Parliament, including those for the increase of trade (3 Mar. 1626) and to limit the number of clerical magistrates (10 March).
After the dissolution Armyne was removed from the Lincolnshire commission of the peace. Although appointed one of the commissioners for the Forced Loan, he refused either to collect the levy or to contribute to it, following the lead of the earl of Lincoln and several other prominent members of the county bench. Armyne spent three months in the Fleet before being committed to the custody of the sheriff of Oxfordshire, remaining defiant until all the refusers were released from custody on 2 Jan. 1628 following the failure of the Five Knights’ case to resolve their predicament.
Armyne’s actions over the Loan did nothing to diminish his local popularity. One of the ‘honest sons of Lincolnshire’ on whom Eliot relied, he was returned for the county in 1628, along with another refuser, Sir William Wray*.
Over the next ten years Armyne opposed the Personal Rule of Charles I at a local level in various ways; he was again dismissed from the county bench for refusing to pay Ship Money, a stance he maintained even when appointed sheriff of Huntingdonshire in 1639-40.
