Gertrude Elaine Horstman was born at home February 19, 1930 to Anthony and Gerdena (Vande Berg) Van Ravenswaay. She died February 11, 2014 at Royal Meadows Care Center at the age of 83 years, 11 months and 22 days. Gert attended country school through the 8th grade. She worked at the Co-op Produce candling eggs until her marriage to William Horstman on July 20, 1951. She worked hard as a mother and homemaker, tending to large gardens and enjoying flowers of every kind. Gert enjoyed keeping her hands busy crocheting and sewing and was well known for her homemade bread, cakes and pies. As a teenager, she learned to play the accordion and often played for herself and family. She especially enjoyed gospel music and loved to play Sunday School songs on the piano for her children and grandchildren. Gert was a long time member of Carmel Reformed Church, serving as Librarian and Catechism teacher as well as Ladies Aid Bible study leader.
