It is interesting that she remarried to a Reynolds but she is listed on the Oregon death index as Hankin, with spouse as Nathan: Name: Hankin, Elizabeth County: Portland Death Date: 1 Jan 1937 Certificate: 6 Spouse: Nathan
I found the divorce listings in the Oregonian, however I didn't find the actual case records listed in the archives, so you might have to check with Multnomah county. Yes, the actual wording is who filed against whom. I subscribe to a service for the Oregonian archives, so a link isn't possible.
Another interesting, yet amusing item I found was that Elizabeth challenged an estate claim:
The Oregonian January 14, 1927 Page 15 Estate Suit Halts While Mrs. Elizabeth Hankin was on the witness stand in Circuit Judge Tucker's court, testifying in her own behalf in a suit seeking to recover a claim of $320 against the estate of John Keubrich for board she alleged she gave him before his death, an attorney for the estate learned that formerly she was a Mrs. Jager through a previous marriage. When her identity was thus made known the attorney recalled that the estate held a note against her and her ex-husband for a loan granted them by Keubrich. Upon this showing Judge Tucker adjourned the case for 30 days to give the defense an opportunity to bring a counter-claim suit.
June 5, 1919 Filing date Nathan against Elizabeth, desertion
April 28, 1930 Filing date Elizabeth against Nathan
Such a colorful couple. Glad to hear that you found your proof! Laura
