Alexander Logan migrated from Canada to Australia around 1855. He married Eliza Collins in Sydney in 1858. Eliza arrived from England in 1856. They initially lived in a rugged sawmilling town north of Sydney where most of their children were born. They then made the 800km journey further north to the Tweed River. Travel was by sailing boat and horseback over mountains. They built the Junction Inn and Eliza Logan Store at Tumbulgum. Alexander was known as Captain Logan and he ferried goods along the river. Eliza's nephew built the first Masonic hall in the district. Descendants lived along the river as sailors, farmers, publicans and shipbuilders. One died while mining in Africa. Another was a successful businessman in Brisbane. William had a cordial factory in Armidale and was a noted photographer. His twin, Lightly Thomas, sailed the Pacific, and had a range of businesses. Joseph Alexander was a shipbuilder. Maggie, a family favourite, and Paul, the youngest, inherited the bulk of Alexander's wealth.
