Thanks for the information! William Alcorn, Horn Head, was born in 1811. His wife Margaret Doel was born in 1821. William's father was Gustavus (Gustavious) Alcorn, and Margaret's father was William Doel. If Gustavus was 30 years of age (more or less) when William was born, Gustavus would have been born around 1781. This takes us back one more generation.
