Catharine Switzer passed away on March 6, 1852 and just over a year later, Jacob married Leathy Bricker, on March 10, 1853.
A month later, on April 11, 1853 Daniel Deemer and his wife Susan, sold the same land they had purchased in 1847 to Jacob Switzer for $2200.
Did Catharine's death and Jacob's subsequent marriage null the original contract, which provided certain benefits to the survivor of them including the house where they lived? Perhaps Daniel (or more likely his wife, Susan) decided that they didn't want to provide for a step-mother? Regardless of what the reason was, which we will never know, the land returned to Jacob in a rather straight-forward transaction.
