Cassie, I found this:
Petition of Louis Hahn in the matter of the estate of Amelia Hahn, for Letters of Guardianship for Louise Hahn, aged 10 years. She is entitled to $98.02, her distributive share under a partition decree in the case of Hahn vs. Gragert. The petitioner is father of said minor and desires John Hahn to be appointed guardian. Bond of $200. Approved by Judge Wilson.
Centralia Sentinel, July 19, 1916, Pg 8.
There was another article on July 25, 1916 listing guardianship for minors Earnest Gragert, 17, and Albert Gragert, 14, with Henry Gragert, 20, filing for the guardian's bond.
Couldn't find anything at all on Louise.
