Hello Ehrsam Hunters, I have Ehrsam genealogy dating back to 1615.They were weavers, living in Weiningen, Canton Zurich, Switzerland.
My grandmother was Emma Ehrsam, daughter of Rudolf Ehrsam, who was Henry's (Henri, Henreich) brother (Henri married Armenta Good).I have a color picture of the house Rudolf and Henry were born in.It's a beautiful Gasthaus now, called Gasthof Lowen (Lion's Inn), in Weiningen.
Here's their genealogy: Ehrsam Hans Jakob17 Dec 1823 - 2 Jan 1907 Married Marie Obrist 11 Nov 1850 she died 7 Dec 1854 Child Anna Maria 10 Dec 1850, died 18 Feb 1851
Hans Jakob remarried on 10 Mar 1853 to Maria Magdalena Zehnder (This is Rudolf and Henri's mom)
Children: Jakob 23 Jan 1855 Kaspar 1 July 1856 Johann Ulrich 5 Dec 1856?? Don't know how but died 1933 Josephine 10 June 1859 Rudolf 8 Sept 1861 died in USA Henri (Heinrich) 28 July 1865 died in USA
There are many more Ehrsam families in the document I have, which was personally obtained from a relative of mine, Harold Hutton, who wrote the Centennial history of Rock County.He gave my father all the original info he typed up.There are other pictures as well.I can scan and send.
