Not sure exactly what you are looking for...more info on the Conreich family or how to contact Nick Landau.  Ancestry has an 1857 manifest for Elias and Taubchen arriving London.  There are 1861-1901 censuses for family members.  One changed his name to Conridge.  Ancestry has transcriptions but Findmypast has orig. census records.  Besides using Ancestry's free introductory search from home, you can access from many public libraries.
