The LDS Family Search site as well as Library would only have microfilmed records of any of the Wisconsin Strangite Church in Voree, if they were done by the WPA Project of the 1930's and got copies from the NARA. That is if the WPA was allowed access. The Strangite Sect was in no way, at any time connected to the Utah LDS Church, so they would have no knowledge of what is and where is any of the information you seek.
You might try the online FamilySearch catalog and search what records they have of the churches of Wisconsin. In fact just search "Wisconsin" and see all the catagories they have.
From Wikipedia: "Strang's death and the loss of his Beaver Island settlement were twin catastrophes for his church. Despondent and spiritually adrift after the Strangite organization failed to provide a successor for Strang, most Strangites eventually chose to join what was then known as the "New Organization" of Latter Day Saints. This group had chosen not to follow Young and the main body to the Great Salt Lake in Utah, and would eventually accept the leadership of Joseph Smith III, eldest son of Joseph Smith. This "New Organization" was later incorporated as the Reorganized Church of Jesus Christ of Latter Day Saints, becoming the second-largest body in the Latter Day Saint movement. Today, it is known as the Community of Christ."
