Condolences
The family of JoAnn K. Block has received the following condolences.
So very sorry in the death of JoAnn. She was a sweet lady in the short time I got to know her at Cottagewood while visiting my mom.
she spoke highly of of her husband Elmer and her kids. She was always dressed so nice and she had a beautiful smile. And a giggle.
We are sorry to hear of Jo Ann's passing. Her husband's sister, Martha Block Perry, was my aunt. Jo Ann was a year ahead of me in school at St. Charles High School. She was always a fun gal to be around. May you be comforted knowing that she is in the arms of our Savior Jesus Christ.
