Hi, Don. Julius & Bertha were my Great Grandparents (maternal). Anna Kopplin-Fuller was my Grandmother. I have some information about them that I'd be more than happy to share with you. For ex. They arrived at Ellis Isl. on May 5th, 1892 aboard the ship "Pichaben". Otto was 4yo; Emma was 9 mos., and she was 6 mos pg with Anna. They settled in Muscatine, IA for several years before moving to Rock County. Let me know. how I can help...feel free to contact me by email.
