I am interested in this surname in Westmoreland and Allegheny co. I have a Hugh wed to Mary that has been listed as O'Donly and Donnell. I recently found Allegheny wills with McDonald and Donaldson for a Hugh and Mary and wonder if they are the same people. Hugh and Mary had land in Westmoreland co. they bought in 1805. They had a son Mathew 1799-1874 who wed Rebecca Eckels. They lived in Burrell twp., Westmoreland co and are buried in Plum twp, Allegheny co. Their children are John, Hugh, Mathew, Mary, Rebecca, Deborah, Andrew, Nancy, Nathanial, Elizabeth, Margaret and Martha. Margo
