Kielhorn info wanted

I have found a new possiblity concerning my g g grandfather
William Kielhorn b Germany ca 1840. There is a August Kielhorn b. Jul 1835 in Marienende Hanover on ship Earnestine April 1856 from Breman which is listed in Germans To America Index 1870-1873 on page 81. Of note that William is listed in Index 1865-1875 on page 81also. Does anyone know of a family tree for them or have access to the Book. Family oral history is that William had siblings.
Thank You
