I'm also looking for a Muller family in Cologne, Germany. Henrich Muller b. 1821, wife Caroline b. 1824, children Albert or Elbert b. 1847, Charles b. 1852, Augusta b. 1851, Frederick b. 1855, and Ernest b. 1857. To my knowledge they were Catholic and some were born in Solingen and some Cologne, Germany. If anyone comes across them I would be ecstatic if you let me know. I'm at a brick wall and can't find them on any passenger lists coming to the U.S.
