Input: Question: Does the town where Abernethy was was born have a larger current population than the nearby port town his family moved to when he was a child? Passage:Thomas Abernethy was born in 1803 at Longside in northeast Scotland. While he was a child, his family moved to Peterhead, a nearby port. His parents were James Abernethy, a stonemason, and Isabella Robertson. Thomas had an elder sister, Ann, who was born in 1801, and twin brothers, James and William, who were both born in 1816. Thomas went to sea at the age of ten and when he was about twelve he was apprenticed as a merchant seaman on the sloop Friends. He travelled to the West Indies and twice to Newfoundland. In 1819, he became a greenhand on the maiden voyage of the Peterhead whaling ship Hannibal, which hunted bowhead whales around the eastern coast of Greenland, and in its third season sailed into the Davis Strait on the western coast, where ice conditions can be much heavier. In 1829, Abernethy married Barbara Fiddes, the daughter of a ship's carpenter, and they lived at Deptford, southeast London, near the Royal Naval docks. They had no children.
