Heinbach v Heinbach, a court case in the early 1910s, was between Mary Alice "Mollie" Heinbach and Jesse Heinbach to probate the will of Jesse's father and Mary's husband, Samuel "Sam" Heinbach.
 Samuel's will gave Mary a tract of land near the :Atlas Portland Cement Company in Ilasco, Missouri, just outside Hannibal.
 Sam's children argued that Mary had undue influence over him and the will, pointing to his alcoholism and deteriorating health.
 This case went to the Supreme Court of Missouri numerous times before it was resolved.
 This case was well documented in the book, "Insane Sisters: Or, the Price Paid for Challenging a Company Town", by Gregg Andrews.
