Members of the Thurbarne family had been prominent in the Cinque Ports, particularly Hastings, Romney and Romney Marsh, since 1331.
Thurbarne never served as a jurat of New Romney, where he owned a house and garden worth an estimated £2 per annum,
Thurbarne appears not to have performed any legal duties for his home town of New Romney until 1601, when he aided the corporation in its jurisdictional dispute with Lydd.
In 1599 Thurbarne married Mary Sudall, the widow of a London Haberdasher. The match may have proved moderately profitable: Mary inherited the lease of her late husband’s town house in Aldermanbury plus £1,000, but was obliged to set aside £600 for her children by her first marriage.
Thurbarne was elected to Parliament for New Romney in November 1620 after writing to the corporation. He had represented the borough in 1597, and at his request it was resolved that he should be awarded wages of 4s. per day rather than the usual 2s.
because he is a very able and sufficient man to do the ports good service at the said Parliament and this town in particular if there shall be occasion to employ him, and because his charges for himself and his man lying there and attending of the Parliament will be more than former burgesses have been.
However, on 4 Jan. 1621 the corporation agreed to cancel his election ‘for some special occasions’.
‘Sick of body’, Thurbarne drew up his will on 4 June 1627, in which he described himself as being ‘of Canterbury’. Just 12 lines long, and witnessed, among others, by the recorder of Canterbury John Finch II*, it conferred all his property on his wife, whom he also appointed his sole executor, on condition that she use the income from half his lands to maintain his youngest son and eldest daughter. No charitable bequests are mentioned.
