Alberton is an unincorporated community in Howard County, Maryland, United States.
[1] Alberton was the site of a large cotton mill along the Patapsco River, founded by James S. Gary after moving from Connecticut in 1839.
A store and seventy company buildings for workers were built on 820 acres around the factory.
In 1866 and 1868, the mill was damaged by flooding, which Gary survived by floating with his daughter on a log.
In 1870, James Albert Gary inherited the mill and the town named after him, "Alberton".
