Roberta "Siss" Lynn Isenhauer

Roberta "Siss" Lynn Isenhauer, age 64, of Frederic, MI passed away peacefully at her daughter's home in Grayling surrounded by Kristine, Jordan, and best friend Nikki on Friday, October 24, 2025.

Siss was born on December 16, 1960 in Grayling, MI to Robert and Marguerite (Williams) Welch. She enjoyed crafting and rock collecting. You could always find her soaking up the sun, going camping, and loved having campfires, even if it was downpouring rain. She was always the life of the party and a go-go person, always on the move. She was very generous and would do anything for anyone. She loved most being with her friends and family and spending time with her children, grandchildren and great-grandchildren.

Siss will be deeply missed by her children, Kristine (Jordan), Ike (Crissy), and Travis; grandchildren, Derek, Erin (Hunter), Madison, Devin, Eli, and Rylee; great-grandchildren, Klaire, Myles; and brothers, Kendall and Tracy. Siss is preceded in death by her parents, and brothers Duane and Donny.

Siss's family would like to thank Compassus Hospice and Munson Healthcare-Grayling Hospital for all of their support and care during her last days.

A Celebration of Siss's Life will be held on Saturday, November 22, 2025 at the Grayling American Legion from 2 to 5 pm.

Arrangements entrusted to Sorenson-Lockwood Funeral Home.
