The only thing that I have run across so far is the emmigration application in October of 1847 for Lorenz along with one made at the same time and place for a Magdelena (possibly a sister), born in Rexingen, Horb distrcit and settled in Ohio, Hamilton Co., Cincinnati 10th ward. (1850 census). I have a hunch that the Konrad you're looking for may have settled in Wabasha Minnesota. I can't confirm this. Unfortunately these are not names of my tree and the only info I have on these names with corresponding dates is as I have given. I will add them to my list of "watch out fors" and will let you know if I find anything more concrete. Best of luck in your hunting.
