The Craig family of St. Andrews, New Brunswick are descendants of David Craig and Mary Steele, loyalists who settled in Chamcook, New Brunswick. David Craig was born near Edinburgh in Scotland on October 1749, while Mary Steele was born on May 1758. David Craig was a weaver by trade but was also attached to the 74th Argyle Highlanders, a Scotch regiment which was tasked with defending the Penobscot River area during the American Revolutionary War. The 74th Argyle Highlanders fought alongside the British against American Revolutionaries at Fort George in Castine during July 1779. Mary was with David Craig in Castine during this time, and together they had two children who were born in Castine: Jannet Craig, born December 1779, and David Craig, born May 1782.

After the Revolutionary War ended it was decided that the boundary between British North America and the United States would be the St. Croix River instead of the Penobscot. Loyalists settled along the Penobscot were forced to move elsewhere, David Craig and his family among them. They moved to St. Andrews in 1784, and David Craig and other members of the 74th Argyle Highlanders were granted land along the east side of the Digdeguash River as well. David Craig lived with his family near the Digdeguash until 1799 when he sold his Digdeguash lots and purchased land in Chamcook, likely to be closer to St. Andrews. During this time David and Mary Craig had six more children, which included Elizabeth Craig, born September 1784, James Craig, born September 1791, John Craig, born September 1791, Mary Craig, born May 1794, Martha Craig, born December 1797, and Allen Craig, born November 1805. David and Mary Craig spent their last years living with one of their daughters, Mary Craig, in St. Andrews. Both are buried in the Old Burying Ground of Greenock Church, St. Andrews.
