Here is the info I have on Michael and his tree:

Michael was born in 1851. Fourth son of Christopher (1812-1889) and Margaret (Zeilman) (unsure of years-1829-1871) Bogner. Christopher's parents: Johann (1786) and Katerina (Bopp) Bogner. Margaret's parents: John (b. 1800) and Dorothy (Redel) (b. 1799) Zeilman. Johann Bogner's parents: Johann and Anna (Hartman) Bogner. John Zeilman's mother: Elizabeth Haverstein. Dorothy Redel's parents: John and ? (Krodtlin) Redel.
(I have nothing for Katerina Bopp.)
Hope this helps! If anyone has anymore info, I'd love to see it.
Thanks.
