Looking for Johann Huffman

Johann Huffman was my GGGrandfather, he was born 28 May 1847 in Germany and died 27 March 1915 in Louisville, KY., USA. He married twice, first to Christina Scharrer {my GGGrandmother) and then to Catherine Goldman. If anyone would have more on him, I would greatly appreciate it. Oh, I have the location of the cemetery where he is buried and I have been there taking a picture.
