I have excellent records on Michael's son Marion Kiefer, but little information about Michael. Believe he was born in Pennsylvania, August 7, 1819 and died in Roll,Indiana, October 6, 1900. Married to Cathern Elizabeth Shively. His father may have been Henry son of John Peter and Eva Schmahl Risinger. John and Eva were married in York County, Pennsylvania in 1752 or 1753. John Peter Risinger and his father Hans Nichlaus Risinger immigrated from Germany in 1749. They are listed on the manifest of the ship "Dragon".Glad to share any information I have.
