The first thing to understand about searching for information on this site is that there is no single search engine for all the data. That is, you cannot search for, say "royes", and get a result including people's names, histories, articles, photos, etc. the way a Google search wil do on the web.
There is a search box for looking up names on the RRFL home page, but you can search for a lot more than just surname and first name(s).
