Hi Guerin,
the Surname Interests Table (SIT) will tell you the names of any RootsChatters
who have entered that they are searching for these names. The name is always a link to their profile, and from there, you can either send them a PM asking/giving more details, or just look at their last posts to see if "your" names come up.
But not everybody uses the SIT (I notice you have

) so another posiibility is to click on the "Search RootsChat" button at the top of the page and enter a name there. With common names, this won't be a big help, but try GUERLIN, there are a couple of searchers there who aren't in the SIT.
Enjoy RootsChat, and if you have any problems, just ask - there's always somebody around, willing to help.
Bob
