[OL]uchtman or uchtmann

hi, my name is Donald g uchtman, I live in Missouri. I have started to look
at some lineage on the uchtman?n and looks like you have gone way back. I
can't find for sure when uchtman's came to us, but looks like about 1840's
and most settled over in ill. I would like to find johann
cord[Conrad]uchtman and his father and mother think he was born in about
1788 in oude pekela. I think the name is the same w/or w/out the second
n.some of the stuff has them from Hanover and some in verrel.thanks
