We to have alot of Peter Dickman in our family too, Carl Peter borned 1853, Casper Peter borned 1808, Charlies Peter borned 1867, I know of not one of them marring a lady with that last name . What our the names of your Peter Dickman brothers, I also know that they used the name Dicrkmann? Dieckmann? (his hand writing is hard to read) as Casper Carl Dickmann signed his Missouri Militia enrollment papers in 1862 (he didn't get in because of his age). I have found that he was from Bovaria Prussia which is now German, he was married when he got here and there were 4 children and some of them were married themself, most of his children were borned in Dresden Prussia. One of his children borned in 1853? had a boy in 1861 who had a child in 1894 and lived to be 101 years old, his name was Alvin Dickman, there was a big write up when he truned 100 on June 22,1994 in the Jackson MO Cash-Book Journal. I would love any info I can get and will help you if I'm able.

HAPPY HOLIDAYS DProffer
