I think there's a limit on the number of profiles that are displayed in a search ... 100 I think. At the top of the search for George Hill you will find something like: .... 100 out of 298. If you sort by birth date and go to the bottom of the list it does not go to 1870. Ah, but all is not lost ... at the bottom of the search page you can refine your search ... add in the birth year (1870) and, voila, there he is (after you sort by birth date again), about 8 lines down. You can choose to exclude profiles without birth dates and the list is much shorter.
