He was born in Glastonbury and served as a lieutenant in the British dragoons. In 1749, he went with Edward Cornwallis to Halifax. He served in Cornwallis' militia.[2] In 1753, he relocated to Lunenburg. Creighton was a justice of the peace and captain in the militia; he later became lieutenant-colonel. In 1753, he was named a judge in the Inferior Court of Common Pleas and, in 1776, he was named a judge for the probate court. He was unsuccessful when he ran for a seat in the first election held in Nova Scotia, but did get elected to the 5th General Assembly of Nova Scotia in 1770. In 1775, he was named to the province's Council,[3] but he was only able to attend infrequently, and his seat was vacated in 1788 after not having appeared since 1785.[1]
He led the armed resistance to American privateers in the Raid on Lunenburg (1782). He and five others defended the town by firing at the privateers from the Blockhouse, wounding three of them. The privateers captured Creighton and the five men, two of whom escaped. The privateers burned the blockhouse and Creighton's home. Creighton and the three others were taken captive to Boston. The lead privateer Noah Stoddard would later report of his prisoner Creighton that "I have a great regard for the old gentleman."[4] He eventually returned and died in Lunenburg in 1807 and is buried in the crypt in St. John's Anglican Church (Lunenburg).
