Without making a trip to Ogle County's library for a township plat map, I am unable to pinpoint where Rasmus and family had lived in 1900.
Listed above is a 2000 map of Ogle County, Illinois. Flagg township is bordered by Gurler Road on the south.
Lee County is directly south with Alto township (home of Ole Jr & Ole Sr) to the southeast and Reynolds Township (home of Rasmus) just west of Alto township.

I think I had come across a similar site when I was looking for maps of Milwaukee, Wisconsin, but this one seems to be more comprehensive.
Thanks you.
