Henry Juncken was a hat maker and a British loyalist who lived in Philadelphia and Quebec City. He was born Johann Heinrich Juncken on 11 April 1735 in Durlach, Germany, son of Johann Ernst Juncken and Christina Dorothea Juncken. Henry moved with his family to Philadelphia in approximately 1753, where they settled. He married Anna Barbara sometime afterwards. Henry was imprisoned for 10 days in 1777 for harboring loyalist sympathies, and fled with his wife to New York when the British evacuated Philadelphia. He migrated to England in 1781, and then settled permanently in Quebec City in approximately 1783. There, he established himself as a hat merchant, a business that he eventually shared with his nephews William Hall and Johann Ernst Rees. Henry died in Quebec City in 1802, after which his wife moved with their nephew Johann Ernst Rees back to Philadelphia.
