Colletta Joan (Wyffels) Louwagie was born February 21, 1934, in Minneota to Albert and Christine (Jennen) Wyffels. She received the sacraments at St. Edward Catholic Church in Minneota and graduated from Minneota High School in 1952. She met David Louwagie at Saturday dances, and they were married September 15, 1956, at St. Edward Catholic Church in Minneota. Together they were blessed with three children. Colletta was a strong, hard-working woman who liked to stay busy, holding many jobs outside the home. She believed farming was a family affair, a generational team effort, and always alongside her husband, David with John Deere equipment. Colletta was a fan of Terry Redlin art, played cards with her card club, enjoyed gardening, making fleece blankets, playing solitaire and casino trips with David. Always a planner, Colletta carried a pocket calendar everywhere, and ended each day with a nightcap of blackberry brandy. Deeply rooted in her Catholic faith, Colletta was a dedicated member of St. Michael Catholic Church in Milroy, where she was active in the CCW and gladly volunteered whenever she was needed. Above all, Colletta cared for her family; she watched over them, spoiled them with treats, and generously supported her 10 great-grandchildren.

Colletta is survived by her children: Steven (Karyn) Louwagie and Cristine Knott; grandchildren: Ashley (Brad) Penske, Stuart (Katy) Stroman, Jonathan (Anna) Knott and Nicholas Louwagie; great-grandchildren: Everly, Barrett & Luella Penske, Jaden, Lucas, Blake, Logan & Brady Knott and Parker & Meadow Stroman; sisters-in-law: Maurine (David) Knott and Karen (Rick) Louwagie; and many other relatives and friends. She is preceded in death by her parents, husband David, daughter Roxanne Stroman and brothers Elmo and Lewis Wyffels.
