The bride and groom acquired their marriage license in Itasca County, Grand Rapids, Mn. With that license, they had the latitude to marry anywhere they chose. It may be that the Itasca Co. court house was close to their residence and more convenient and yet married in St. Louis Co. for some reason. In addition, I am not certain on the spelling of the witness as "Gill". I spelled it as it sounded phonetically as that but there may be another spelling so please keep that in mind.
If you need add'l. help, just ask. May I provide my email:firstname.lastname@example.org
