They had three children: Laurie, Lisa, and Alan.

Janet was a hard-working homemaker. She loved God, life, and her family. Janet was happiest when being outdoors. She loved helping Jim in the fields, putting in a large garden and canning everything she fed her family. Janet loved long walks in the woods, fishing at their lake and mostly she loved the time spend with her six grandkids playing in the creeks, sledding in the snow, and exploring the woods.

Janet and Jim loved to dance, they enjoyed spending time with friends, playing cards, hosting BBQs, traveling, fish fry's, and playing practical jokes on the friends and families.  Janet loved to bowl, attending many tournaments over the years. Janet continued to be very active in her church after Jim's passing until her own health failed. She was a devoted Christian with a very strong faith. Janet loved being a grandma, each grandchild was a true blessing to her and she created a special bond with each and every one of them.
