New Bethel Church records show that a Christian and Susanna had a child, Reuben. This is likely Michael’s Christian and his wife: Christian & Susanna HAGEBUCH; Reuben, born Sep 28, 1803; Sponsors Andrew HAGEBUCH & Maria REIGERDORFER1 Grave records show a Reuben about the right age died in Luzerne County, PA2
May have married Mary. Per the Van Horne Genealogy book “Mary b. 10/3/1807, m. Reuben Hagenbaugh.”
Gravestone has name as “Rheuben Hagenbaugh” and age at death 82 years, 2 months, 4 days. This leads to a birthdate of January 6, 1805. This could work with other known children. Perhaps an earlier Reuben died?
