William Bevil Thomas (b. 1757 in St. John's, Newfoundland; d. 1825 in St. John's), was a prominent merchant, land developer and sea captain who is, with his descendants, notable in the history of that city and in the history of Newfoundland and Labrador province.
Thomas was from a line of merchant mariners from Devon, England and was genealogically connected with many other prominent families in Newfoundland, England and New England.
Daniel Woodley Prowse wrote:
The family of the Thomases are probably the most ancient in this Colony; their connection can be traced back to the Shapleighs (one of whom was grandfather to John Treworgie, the Cromwellian Governor of the Colony), thence through the Bevils to William Bevil Thomas. The Thomases carried on business at Dartmouth and St. John's in partnership with a Mr. Stokes, as Thomas & Stokes.[1]
Treworgie married a woman of Newbury, Massachusetts in 1646 and through her Thomas may be descended from the puritans of Massachusetts Bay Colony.[2][3]
Thomas' shipping operations brought him along a triangular route that included Britain, the Caribbean and Newfoundland. In 1757, he married Elizabeth Way in Dartmouth, England. The couple's two sons, William Thomas and Henry Phillips Thomas, were prominent men in the generation after their father. According to Prowse:
...officials and merchants vied with each other in creating country residences and farms [...] finest of all, Brookfield, the property of William and Henry P. Thomas.
[...] William Thomas was foremost in every benevolent work. As a very young man he was secretary to the society for improving the condition of the poor; he was equally distinguished as a merchant and a politician. He filled all positions well, whether presiding at a religious meeting or as president of the Chamber of Commerce. Through a professedly religious man, sometimes the old leaven broken out him. He was very active, and fond of directing everybody. Often, as he paced his long wharf, if one of his ships was beating in the Narrows, say his fine brig the Cynthia, Captain Goldsworth, he could be heard muttering, "Luff, confound you, Goldsworth, luff, you lubber!' Brookfield, the fine house at Devon Row, their Water Street premises, and the beautiful cottage at Topsail, are monuments to the large progressive ideas of the Thomases, and especially of the constructive ability of Henry Phillips Thomas.[1]
The author also mentions that William Thomas was one of the most prominent Protestant merchants who rallied for a local legislature during the administration of Sir Thomas Cochrane.
