I am looking for information on Katherine Ann Ahern. She was probably born in the 1850s or early 1860s. I am not sure of the place of birth, but could be Maryland.Katherine married Thomas Marion Harrison and they had 10 children. (5 boys then 5 girls)the children are Thomas Kennedy, James, Henry, William Lawrence, Kenneth Leo (born Jan 25, 1886 in MD), Mary Johanna "Mamie" (married a Cooke), Florence (married a Bennett), Katherine Regina (married a Bauer,Helen (married a Cole) and Rita (married a Kennedy.)Daughter Mamie had a house by the Maryland shore.Katherine Ann's father is said to be Michael Ahern, who walked from Pennsylvania to Baltimore and settled there. I would appreciate information on any of these people.
