Glad I could help. In addition to contacting the Union County Historical Society take a look at the Union County Register of Wills estate and orphans court records. They may prove quite helpful. Also be sure to follow up in getting John and Elsie's death certificates, marriage record and obits. Anyone of them may have the data you seek.
