Sharing names

A few days ago, there was a little discussion about the Riddle 
family, with posters clearing up confusions over just who was who, 
and who killed whom.  It's easy to get confused, as there are two 
Tom Riddles to keep track of.  And then it occurred to me...how very 
odd that that would be the case!  It's unusual in Rowling's books 
for a father and son to have the same name.  In fact, I can think of 
only one other example:  Barty Crouch Sr. and Jr.  Now, it was 
significant for the plot that the two Crouches shared a name, 
because it succeeded in throwing a red herring across our path when 
Harry saw the name on the Marauder's Map.  This leads me to believe 
that such an unusual occurrence in the Riddle family might ALSO be 
of use, plot-wise.  Can anyone think of any reasons why Tom Riddle 
would have to have the same name as his father?  Because I really do 
think that it's going to turn out to advance the plot somehow.
