I grew up in Ryde, Wayne Twp, Mifflin Co, PA. and am descended from Alexander Mckinstry thru James Mckinstry and Barbara Harshbarger and their daughter who married Miller (my g-g-grandparents). Most of my relatives are buried in the Mckinstry Cemetery (now Ryde Cemetery) in Mifflin County. I have info on line starting with Alexander Mckinstry from County Antrim Ireland down to myself, which covers 9 generations and many surnames - Samuels, Orr, Harshbarger,Miller, Wharton, Beck, Bard, Butler, Wicks, Bratton, and others.
Will be happy to email any available info.
