Holtz was Holz in German...there is a is a long line of Holz who immigrated to Wisconsin. Many were and are buried in Neillsville, Wisconsin. So many investigated avenues when tracking your family so connect the dots carefully! On Jim Meisner Profile the two oldest daughters of Emilie (Amelia) Langer who married August Ferdinand Dec 1, 1885 and had there first two daughters her in Rock County. Ida Amelia married Carl Kreger the brother of Ernest Kreger who married her sister Emma Amelia. Carl and Ida are buried in Richmond Cemetery near whitewater on Territorial Road, Walworth, Wisconsin and Ernest and Emma are buried on Milton Lawns Memorial on Milton Avenue in Janesville....Ida and Emma's brothers were George, William, Raymond, Helena aka Mrs. Clyde Hanson and the latter of siblings lived in Oshkosh, Wisconsin. While Ida and Emma remained in Janesville and Richmond before there departure. Langer roots go as far back as early 1850's to immigration into Wisconsin while Holtz I am back to late1700's. Kreger's is being researched and is about 1700's thus far too! And now I am hooked and will keep going till I can't no more...but play detective and you will solve the mystery...the clues are placed in peculiar places, but right in front of you...Good Luck!
