I am amazed to see all this information -- and so I wanted to provide some more information on the Minnesota descendants. Frieda Zneimer and her husband Isor Hertz arrived in St Paul in about 1882, with six sons. Christopher Jamison has all this correct. My grandfather Aaron married twice, and my father Marcus is the middle child from the second marriage. He still lives in St Paul, age 83. His older sister Ann lives in Los Angeles, and his younger brother Ervie lives in Florida. All of the others of that generation have died, except for Joseph (known as Dover), son of Harry Hertz, who lives in Dallas. There are dozens of kids from the next generation (my first and second cousins), scattered all around the USA, and more in the following generations.
Fascinating!
