was there murphy twins???

Erin does have a fraternal twin, Diane. But she was fired from Bewitched because her and Erin began to look less and less alike.

Three sets of twins played as Tabitha. The first 2 sets were infants, and then the Murphy twins came in during season 3 at the time that "Tabitha" developed her powers as a little witch.

You can find some pics of the Murphy twins at the following link:

(sorry, it seems impossible to copy and post those images....)

Erin was indeed the primary twin who played as Tabitha once Bewitched was filmed in color, while Diane was used as back-up while the twins still looked identical, until their appearances stared to differ (and I think "fired" is kind of a harsh word implying she was let go due to misconduct......I prefer to say that she was "no longer needed.")

The only ep of Bewitched in which Diane's name was used in the closing credits is "Samantha Fights City Hall" (Erin was out sick during the filming of that ep...)
