A relative retired from farming in the 1910s when his one son took over the operation of the farm and moved approximately twenty miles away.
Five years later, the son was unable to manage the significant debt he had taken on. The father returned to the farm, paid the son’s debts, and the son left the farm to take a factory job in another town.
Because the time period was fairly short and no census years were involved, it was some time before I discovered this relative’s short-lived foray into retirement.
Did your ancestor move away for a short time only to return later? It could explain that short-term absence. That relative you think lived their entire life in Minnesota may have spent a few years in Texas after retirement only to return later to Minnesota.
