Frederich and Catharina had four children. Three in Germany Fred Jr. and William that came over on their own and Henry that came over with them. In Kentucky they had a daughter Anna. Dates are as follows:
Fred Jr. (Frite)
The 1860 census has Fred Jr. as born in 1843 ans 17 in 1860. There are records of him as an ore digger but he disappears from the 1870 census. I thought that maybe he entered the Civil War and after a lot of searching I found an entry for Fred Kottkamp joining the Union Army in 1861 at Muldraugh Hills which is south of Louisville. It as a long way from Carter County but maybe the effort seemed more noble or at least maybe easier than hard rock mining. His military career seemed however brief.

Death in Louisville again:

There were no other documents regarding Fred Jr. and I found documentation that soldiers that died at the Louisville hospital were buried on hospital grounds. After the war the hospital was closed and those soldiers were re-interred in the National Cemetery in New Albany. I went through he records of the National Cemetery using the various spellings of Kottkamp with no results. Eventually I did find a Fred Cotcomb that was re-interred there. Curious, I could find no records of anyone by the name of Cotcomb ever being in the Civil War. If fact there was only a couple of obscure references to anyone with the surname Cotcomb ever and those were in the 15th century. With no further proof I have assumed that Fred Cotcomb is probably a miss-identified and re-interred Fred Kottkamp. Here is a photo of his marker in the New Albany National Cemetery.
