U.S. States: Missouri: Saint Charles County
I do have an Antoine Linhoff who is the brother of Francis, leter this name was spelled Lindoff as well as Londhoff and prolly numerous other I haven't seen.
The Linhoff's I am directly related to settled in St Clement, which is in Pike County outside of Bowling Green, Missouri. They apparently came from St Charles County
Francis as well as Antoine seemed to have disappeared around the cival war period, the children I found to be living with Margret Linhoff all in their 20's in 1880 well youngest son was 18 in 1880 so I know he was around in 1862 and found Antoine and Francisis on the 1860 census but none later then that.
It would help information if we could gather some known dates you have to hook these together somehow
