Testing +Thomas Maynard +Thomas Maynard  +carolynmaynard +Carolyn Maynard +Carolyn Maynard

So: One needs to type "+" followed by the correct case of the first name "T" or "T" -- although in my own case, "t" also works but not for Carolyn.  I'm not sure I understand it fully, but at least I know the secret now. +David Maynard +Martha Patterson ... just like that!
