I have the information that you posted in your reply except for the specifics on the Theede family. If you are interested I can possibly help you with some of Jacobs brothers descendants and ancestors.
My grand father Jurgen (not Jacobs brother Jurgen F.) was a 1st cousin to Jacob. He and Jacob were the first to immigrate to the U.S. in 1866 onthe ship "Tetonia" arriving in N.Y. in November. They then traveled to Macoupin county where they settled. Several years later Jacob moved on to Kansas where I believe he eventually homesteaded land in Rice Co. The rest of Jacob's family eventually followed him on to Kansas. If you want more info perhaps we can correspond directly via e-mail.
