William and Edith were divorced by the time of the 1920 Census, but I have not yet confirmed the exact date. The above clipping was from July 1917 so depending on how long the process took, we could guess they were divorced at some time between 1917 and 1920. However, according her mother, a separation would have occurred around 1911 or 1912. In Chapter 26 of Martha's autobiographical manuscript, she states "In 1908 my daughter married a neighboring rancher, and I was alone for three and a half years. Then she lost her husband, and with a baby daughter came home to live with me again, and we have been together ever since." I would have to speculate that either Martha was uncomfortable talking about a separation or divorce (which is very possible considering she leaves out any mention of her first husband from her manuscript) or maybe Edith and William's marriage was not a good one and not one to be remembered in her "Memories." Martha may have also remembered the timing incorrectly when she sat down to write her story.
