The problem started way before the person who added that to Find a Grave. The photo shows that Rachel and her father-in-law share the same gravestone, which means that whoever ordered her name added to her father-in-law's gravestone was at fault. Even more - her father-in-law's gravestone allowed the space for someone else to be buried next to him and share the stone - how come his wife, who died after him and before Rachel, was buried in a different cemetery in the same town instead of next to him?
