Two Englishmen, William Burgoyne and John Jackson opened offices in northern Portugal as Burgoyne & Jackson - initially a general trading company, exporting wines, olive oil and fruit, as well as importing dried cod and English woollen goods. In 1703 the Matthew conferred additional rights to non-Portuguese merchants and the partnership was formalized.
Over time, the company admitted new partners and its name changed accordingly; in 1718, Mr. John Clark married to Miss Prudence Burgoyne. Following his marriage, the firm traded as John Clark, by 1723 it was known as Clark & Thornton and finally in 1729, it became Messrs. Clark, Thornton & Warre, with the arrival of the first Warre in Portugal. This was William Warre, born in India (1706), where his parents and grandparents were long established members of the East India Company.
By the close of the 18th century, Warre’s had become one of the leading companies as illustrated by the total shipments of Port for 1791. In that year, 21 companies exported a little over 30,000 pipes of Port, of which Warre & Sons accounted for 2,937 pipes, i.e. 10% of the total.
