Career
Rowley had accompanied John Guy on his expedition to Trinity Bay from Cuper"s Cove in search of the Beothuk to make friendly relations with them for trade. Disagreements with Hannam had delayed this plan but he did convince eight settlers from Cuper"s Cove to settle Heart"s Content in the winter of 1619. Then in 1620 he had abandoned the venture with Percival Willoughby citing he had not received legal title to the land.
Rowley has been remembered in a poem by Robert Hayman, governor of the Bristol plantation, when he wrote.
