I think this maybe what you are looking for. https://www.tribalpages.com/showcase.html There is a search box top right and then it also list other TribalPages websites below.

Was you ever able to locate the search box on either the home page, or any page for that matter! LOL! Like you, I have not used this site for a while, but am back now to find I am now totally lost. Every search box I have tried only seems to search my page. I would like to search the whole Tribal pages.com website for a Surname.
