Thanks for mentioning your schedule. Yes I'll be off of this tomorrow also.
You asked about the meaning of this: "10-16-1874 Jackson Co WI...Hannah LOW d/o James & Susannah HUTCHINS m. John Frederick SAUTER s/o John & Christiana."
It means that on 16 October 1874 in Jackson County, Wisconsin Hannah Low, daughter of James and Susannah Hutchins married John Frederick Sauter, son of John and Christina [Sauter]
In other words, the person who found this record is saying David Lowe's wife Hannah seems to have remarried in 1874. Oftentimes a woman who had been married previously re-married using her married surname. The maiden name of the Hannah above is Hutchins, since her father is James Hutchins.
Thus you've found the names of the parents of Hannah Hutchins, and if you didn't have the names before, that's big news!
