Mary Ann Fenstermacher, age 85, passed away at her home in Seaville, NJ on Thursday, November 12th 2020 in the presence of her son, David and husband, Joe. She was born on December 2, 1934 in Kosciusko Twp., Day County, SD and lived in SD, MN, IA, MI, MD, NJ, NY, and ME plus Switzerland and England. She graduated from Sisseton High School and Augustana College, SD and taught at Elementary Schools in Rochester, MN and Lansing, MI; later Mary worked as a secretary and office manager at the National Library of Medicine (Bethesda, MD) and the Department of Orthopedics (State University of New York at Stony Brook, NY) until retiring in 1994. Mary was a member of various churches during her life, for instance Christ Lutheran in Bethesda, MD and St. Paul Ev. Lutheran, Grosse Pointe Farms, MI; at these churches she sang in the choir, taught Sunday School, and participated in various woman's groups and activities. She enjoyed walking, jogging, and bicycling. Mary loved the family farm in the Glacial Hills of SD, the cows that lived in its fields, and the country church, Zoar Lutheran, that was located on the northeast corner of the property. She welcomed her children's friends, one of whom gave her the affectionate name of "Moda," which stuck and became her familiar name to one and all. Mary was very easy going and tolerated her son's "garage band" that played many a night in the recreation room of her home in MD. Survivors include her spouse Joseph D Fenstermacher, and children Paul Fenstermacher and his spouse Lisa Fenstermacher, David Fenstermacher and his spouse Julie Savage, Jim Fenstermacher and his spouse Niven Yassen, Sara Soens and her spouse R.J. Soens; her brother Richard Bue and his spouse Mary Ann Bue, her brother Harvey Bue and his spouse Doris Bue, and her sister Delores Natwick; grandchildren Matthew Soens, Eric Soens, Jana Fenstermacher, Elise Fenstermacher and Adam Fenstermacher. Mary was preceded in death by her father Conrad Bue and mother Belle Bue, and her brothers-in-law Phil Natwick and Jack Fenstermacher.
