Ever wonder where the name Anderson came from?  I mean, why that name and not something else?  Could it be from a reference in The Five Orange Pips, where Watson is writing in passing about previous cases and mentions "...the facts concerned with the loss of the British bark Sophy Anderson"? 

It's a very slight connection.  If the name of the ship had been Sally Anderson, then I would be a lot more sure the TV names were a nod to the canon!

The name Anderson is mentioned in The Hound of the Baskervilles, chapter Fixing the Nets:
"Students of criminology will remember the analogous incidents in Godno, in Little Russia, in the year ‘66, and of course there are the Anderson murders in North Carolina, but this case possesses some features which are entirely its own."
It's probably just a coincidence, but it is still funny - Anderson? A murderer? LOL
