Kurtz in Wisconsin

I'm trying to find anything about my Kurtz roots.

Jacob Kurtz 1809 in Prussia, d. 1896 in Koshkonong, WI. Marries Suzanna Klein they had George Jacob, Christine, Sophia, John & Harriet - all born in Prussia except Harriet. She was born in WI in 1851.

George Jacob married Katherine Hetts (b.1841 Baden, Germany) and they had George Jacob Jr, Mary, John & Catherine (Kate.)

George Jacob Jr. married Louesa Striegl, they had Lela, Carroll, Hans, Norman (my grandfather), Maynard and George Thomas (Tommy.)

Norman married Margaret Berg & they had Dorothy Lela (my mother) and William Maynard.

Does anyone know anything about any of these Kurtz's?
