Robert McNab, along with his wife, Margret Crawford, immigrated to Cape Gracias a Dios on the northeast coast of Honduras. They arrived in 1835 from Edinburgh, Scotland. The English had a settlement on the cape, and there was a fort manned by British soldiers. A few settlers also tried to make a living there.

While there, Robert McNab heard about the Bay Islands to the west and decided to relocate there. The archipelago was beginning to attract British subjects from the Cayman Islands and beyond. When his party reached Roatan, they settled on one of the three cays inside the French Harbour channel.

There is an interesting account of the McNabs from a few years later. In 1840, an Englishman named Thomas Young, an employee of the British Central America Land Company, was on his way to Black River. His objective was to establish an English colony on the Mosquito Coast of Honduras. En route to Black River, Mr. Young’s schooner encountered a problem with the rudder and had to seek help in French Harbour.

Thus the town of French Harbour was started.

Mr. Young states in his writings that a Scotsman with a large family was the only person living there. The Scotsman that Mr. Young refers to in his writings can only be Robert McNab. Young describes the family as well-established in French Harbour. Since the Scotsman was a boat builder by trade, he repaired the schooner for Mr. Young. Mr. Young’s account states that the family was in the process of building a small schooner to trade with Belize, the Cayman Islands and other ports.

Around this time, the Jones family also settled in the town. The two island families began to marry into each other. Thus, the town of French Harbour was founded. Curiously, no one seems to know for sure why the town was called French Harbour, since it was settled by Scots. There is an old, commonly heard story that two Frenchmen were the first people to live there, and thus the place became known as French Harbour.

Robert and Margaret had a total of seven children: five boys and two girls. From 1840 to the present day, descendants of Robert McNab and Margaret Crawford have owned and operated all types of boats. They owned commercial fishing boats, such as shrimp trawlers, lobster boats, and conch boats, as well as general cargo vessels, freighters and, lastly, passenger ferries.
