I am looking for any information available about Johann D. "John" Stalder and wife, Magdalena Schumacher from Switzerland.

John was born 1 Jan 1844 to parents Peter Stalder and Maria Zihlmann in Escholzmatt, Kanton Luzern, Switzerland. He immigrated in 1892 to Henry Co., IA and died 7 Sep 1927 at his son, Joseph's home west of Coppock, Henry Co., IA.

Magdalena Schumacher was born 1 Sep 1859 (presume Switzerland) according to her tombstone. Parents are unknown. Magdalena immigrated in 1893 to join John in Henry Co., IA with 4 sons. She died 9 May 1899.

Children are:
Joseph Frank (or Frank Joseph) b. 15 Sep 1879 in Escholzmatt. Died 23 Jul 1957. Married on 28 Feb 1911 in Mt. Pleasant, Henry Co., IA to Mary Josephine Kauffman, b. 1 Jul 1888 in Escholzmatt and d. 18 Jan 1962. Parents of Mary were Jacob Kauffman and Agatha Achermann.

Emil b. 26 Dec 1882 in Escholzmatt; d. 11 Jan 1967 in Washington, Washington Co., IA. Married 23 Feb 1910 in Mt. Pleasant, Henry Co., IA to Lena Kauffman, b. 12 Jun 1890, Wayland, Henry Co., IA and d. 10 Mar 1976. Parents of Lena were Jacob Kauffman and Agatha Achermann.

Otto John b. 20 Nov 1887 in Escholzmatt; d. 2 Oct 1953, Washington, Washington Co., IA. Never married.

Alfred b. 15 Oct 1889 in Escholzmatt; d. 2 Jan 1950. Married (1) Effie Lena Williams on 3 Jul 1915. Effie b. 15 Oct 1895; d. abt. 1996. Married (2) Emma Kauffman on 17 Apr 1917 in E. Pleasant Plain, Jefferson Co., IA. Emma b. 5 Oct 1892 in Wayland, Henry Co., IA; d. 21 May 1975. Parents of Emma were Jacob Kauffman and Agatha Achermann.

A document in our possession written in German MAY be a marriage license of John and Magdalena showing a date of 11 May 1883. We believe that John may have been married twice and first wife died? Possible that boys are not children of Magdalena?

2 daughters born in Henry Co., IA.
Leah b. 16 May 1895; d. 16 Nov 1967, Washington, Washington Co., IA. Married Anton "Tony" Kauffman on 15 Feb 1914; he died 5 Sep 1953. His birth date and parents are unknown.

Thanks for any help!
