These seem to be the same two who are my Great Great Great Grandmother and Father. I have with me copies I made from my grandparents' family bible which had a family tree done by my great grandmother.
According to this John Alexander Glenn & Mary Rebecca Vogan are the parents of John William Glenn (Mar 3, 1860 in Sandy Lake, PA. -died 1944).
John William Glenn was married to Sara Araminla Davis (March 11, 1870 Blacktown, PA) and they had Joy Adelaide Aurand Glenn (July 28 {or 29}, 1904 Sandy Lake, PA -died Sept 14, 1991 Warren, OH)
Joy Adelaide Aurand Glenn married Boyd Stitt Burd (Aug 8, 1807 Academia, PA -died Aug 11, 1983 @ 3:30am Warren General Hospital) and they had Joe Brady Burd, Boyd Glenn Burd, and Linda Elsie Burd who is my grandmother still living and married to my grandfather Roy (or Ray) Lee Townsend who is also still living.
