Jacoba "Cobie" Spoelstra was born February 26, 1939, to Jelle and Anna (Kuiken) De Vries at their home in Slootdorp, Noord Holland, the Netherlands. Cobie and her family immigrated to the United States in 1949, and settled near Leighton. Cobie attended Pella Christian Schools.

On June 3, 1960, she was united in marriage to Bernard Spoelstra at the Calvary Christian Reformed Church in Pella. To this union they were blessed with four children: Rick, Michael, Brenda and Timothy.
