This Frederick Abe only seems to exist in the family stories passed down through "The Abe Family Heritage" books published since 1982. I have not found one record that mentions him by name. The story is told that he was born in Germany and came to this country in the 1830's with his parents John Adam and Annie Catherine Abe, and his three brothers Nicholas, John and Augustus. The story further states that Frederick at some point went west to Missouri. The (2)1840 Census does not list any children by name but does list two sons that fall into the 1820-1825 birth age group. The other child in this group would be John Abe (see posting 10-008). No other records have been found to substantiate his existence.
Please see the post "John Adam Abe and Annie Catherine 10-002" for further information.
