Let's retire the fiction that Otto Plath and first wife Lydia Clara Bartz Plath, married in Washington State in August 1912, were together for three weeks only, because records continue to show it was closer to three years. In 1914 Otto was teaching in Berkeley, California, living with Lydia, and both were registered to vote -- as Progressives. Here's their voter-registration page. [Click the image to enlarge.]
Wait, but it's 1914, so women in the U.S. can't vote!?! In California they could and did.
Otto and Lydia are still at that address in 1915 as she enrolled in UC-Berkeley's summer school.
