It appears that Jack Koberstine (born 27 Jul 1921) was married to Elizabeth Koberstine as they both ended up in Michigan. The movement of Jack to Michigan is given from death record. It seems likely Jack Koberstine (born 17 May 1888) may be his father, as suggested by the first names being Jack, i.e. Sr. and Jr.
