Your grandfather is part of my family tree (my Mom is a Jens). I have his name as Eggert, born April 4, 1885, married to Nora Hayden. The other sibling names are: Helene b 1891, Heinrich (Henry) b Aug 25, 1887, Fred Marx b march 15, 1883, Jergen (Jerry) b Nov 11 1879, Lena b May 13 1877, Dorothea b June 22 1875, and Johann (John) b July 20, 1873. Their parents were Marx Jens (June 29, 1850 - April 26, 1925)and Anna Heesch (b April 22, 1849 - March 29, 1929). Marx had two brothers: Johan 1846-1877 or 78, and Ed (Eggert) Jens (b Jan 13, 1847 - Feb 6, 1926). I'm decended from this Eggert. Marx's parents are Johan Jens who died at age 36 in Schleswig, Germany and Lena Ruge. Lena later remarried Bartholdt Hamann and had three more children (Claus, Mary and Stephen). That's about as far back as I've been able to go. If anyone has any more information, please share! I know most of the family is from Schleswig-Holstein Germany, but I haven't been able to track them down.
