If you are looking for Duggans in Texas I believe that they came from Edmund Duggan. He came to Washington County, Ga around 1797. His mother was named Chloe. He had a brother named John this is whom my family came from. There father was named William. they came from North Carolina. William was born c.1750 died c.1797 married Chloe Ann Hyman c.1770. William served in the Revolutionary War. Edmund left Ga and married an Alston I believe in Mississippi. I do know his family went to Texas.
