Bonnie Irene Filter, 79, of Waterloo unexpectedly passed away and went to heaven on Friday March 19, 2021 at Watertown Regional Medical Center.

Bonnie was born on October 26, 1941 the daughter of Emil and Vera (Doschadis) Hensler.  She grew up on a family farm in Waterloo and was the youngest of 9 children.  She married James Filter on May 2, 1964 and enjoyed 30 years of marriage before his passing in March 1995.

In Bonnie’s free time she enjoyed watching Badger and Packer games, tending to her flowers, reading books on her Nook, baking cookies, and attending all activities her grandchildren participated in.  To get away, she loved spending time at her cabin in Finley, Wisconsin.

Bonnie will be remembered for the caring and love she showed to everyone that was close to her, especially her grandchildren.

Lutheran Church on Thursday, March 25, 2021 from 11:00 am until 1:00 pm.  After the visitation there will be a private family funeral service at the church with Pastor James Adomeit presiding.  Bonnie will be laid to rest next to her husband at Oak Hill Cemetery in Waterloo, Wisconsin.
