Hi Sandy, I haven't been able to find a death record for Frederick yet but I do have some info for you. On the LDS sight if you look under Cathrine Ringstoreff you will find their marriage in Louisiana. Also at Ancestry Look up Frederick Hammen and you will find them in Hallock Township, Peoria county in 1860 census, they were living with some people that I have never heard of and they miss interpeted the birth place for our gg grandfather as Dominica but if you look at the original image and blow it up you can see it says Louisiana. I hope this helps you and if you find any more info let me know. Later cuz, Dennis.
