In my genealogy research I have a Daniel Barr m. Emillia Cahill. There were eight children in her family. John b. 1805 in Pennsylvania, Joseph b. 1798 Park County, Ohio ( but there is no Park County), Mary Cahill b. 1800, m. Jacob Middleton, William, b. 1796 in Virginia, Alexander, Elizabeth, Jane, Rebecca, Thomas, and Dennis, b. 1799 in Ohio.-- I'm still researching this area of my tree.
