Yes, but in the best possible way! I actually think its really awesome...
I made the connection as well. I wouldn't mind it as far as the show goes. I'm just not a huge fan of Tabitha for other reasons. But I doubt the show would make anyone think anything bad about it.
I think it would be hardly noticed by the younger set. The show has been gone a long time. I really liked the show when I was a kid. When I hear Tabitha now days I think of the hairdresser that whips everyone into line :)
I did make the connection, but I love that show and love those names! I adore Tabitha.
I would notice (I think of bewitched when I hear Tabitha, anyway!), but it's not negative and would be an easy association to get over.
I'd make the connection but it would be more of an, "Oh, I just noticed that," than anything. The names fit together to me because of the -tha and "heavy" A usage. It has nothing to do with the show Bewitched.
Not that that's a terrible thing!
I might notice, but I think it is cute. I love Tabitha.
