Here are some excerpts from the book, "History of Madison County, Iowa, 1846-1984"; history & biographies, written by the people of Madison County and compiled by the Madison County Genealogical Society, printed by the Taylor Publishing Co., Dallas, Texas.

    In 1860 Gerhardt Storck married Wilhimina Marquardt, the daughter of Carl and Dorothea (Schaka) Marquardt. In 1870 Gerhardt and Wilhimina moved to Madison County, Jefferson Township to set up farming. (For a time after the death of Dorothea Marquardt, Mr. Marquardt lived with the Gerhardt Storck family).
    Gerhardt and Wilhimina were the parents of twelve children, some of whose descendants still live in the area.
    During the early years, the Storck family home was the home for the circuit-riding pastors as they made their rounds. There is a room fondly remembered to this day as the "preachers room". Church services were held in the Storck home before the church was built. The land for the Trinity Lutheran Church, parsonage and cemetery was given by Mr. Storck. The Storck family was always ready to help and befriend those in need and were greatly loved and respected by their community.
    Mr. Storck also built and maintained the Storck School which was in the grove north of the family home.
    Mr. Storck died first, leaving his wife Wilhimina in charge. At the time of her death, each child was left with a farm. The will of Mrs. Storck was one of the most intricate wills ever processed in Madison County. It is at this time that the family farm was passed on to their granddaughter, Marguerite Wehrkamp Brooker.
    The original buildings from the 1870's still stand. Many of the century old evergreen trees stand at the time of this writing.
    Many of the family heirlooms and belongings still remain in the family at the homeplace. Many memories are present at this home and the nearby Trinity Lutheran Cemetery is the resting place for most of the family members.
