Q How do I link one Person Page to another Person Page
A There are a couple of methods....
When editing any wiki page the "Wiki Link" tool represented by the icon which looks like a page with a chain (link) on it can be used. It allows you to enter the text to be shown, for example "William Reeves" and separately the name of the wiki page containing that individual, for example, "Reeves_William_41"
Alternately one can achieve the same by directly typing in the wiki page ((Reeves_William_41|William Reeves)) which appears as William Reeves or ((Reeves_William_41|Reeves, William)) which appears as Reeves, William but both go to the same wiki page.
