I'm looking for the parents, grandparents, etc. of Jane (Jenny) Elizabeth McCague, b.1831, Harrisburg, PA. She married Rufus Silvester Riley in Cleveland, OH. They both died in Glendale KY between 1910 and 1912. They were my grandmother's maternal grandparents. I would guess that I'm looking for McCagues (arriving from Ireland or Scotland?) in PA in the early 1800s or late 1700s. Thank you for any help.
