Mabel Cass & friends (or family)

Here is a photo of my great grandmother, Mabel Cass (far right) and two other children.  I'm not sure whether they are friends, cousins or what their relationship may have been to Mabel.

This photo was probably taken in the late 1890's or around 1900.

The Cass family moved from Hancock, Waushara County, to Fort Atkinson, Jefferson County, Wisconsin sometime after the 1895 Wisconsin Census and prior to the 1900 US Census so I'm not sure where this photo was taken.
