I'm seeking information about the ancestors of Ellen Gallagher b. ~1823 in Cork, Ireland, married on April 15, 1849 to Michael Mortell in Burlington, Vermont. They lived primarily in Illinois (Chicago and Kankakee) where most if not all of their 11 children were born.
Children: James, Honora,
John, Edward, Ellen, Michael, Patrick, Anna, William,
Margaret and James.
Ellen might have arrived in the United States in 1839 on the ship Erin at age 16, but that's not definite. Another possibility is that she came to New York on the Columbus in 1848, but that would have given her only a year to arrive in Vermont, meet and marry Michael.
Any information or leads as far as her parents and ancestors would be greatly appreciated.
