Darrin hails from Missouri and served in the United States Army. His old army buddy, Adam Newlarkin, visits him in 1965 when he is in town to look for a new job. Darrin went to college with Charlie Harper and Daphne (whom Charlie later married), although Darrin does not remember her when they meet again in 1967. Daphne said Darrin was the only red-blooded American male who never chased her around the quad.
Darrin was initially engaged to Sheila Sommers, a beautiful but vain and snobbish woman. Darrin married Samantha while Sheila was vacationing in Nassau. Sheila does not like Samantha and tries to humiliate her at every opportunity.
Dave is Darrin's drinking buddy and best friend.
Marriage and Family
Darrin met Samantha, fell in love and married her in 1964. He took her to Atlantic City for their honeymoon. At the hotel on their wedding night, she tells him she is a witch and proves herself. At first, Darrin does not know what to do, but decides he loves her and cannot give her up. He wants Samantha to learn to live like a mortal, believing witchcraft is not a "proper" way to live. Samantha complies, but cannot give up her witchcraft completely. Darrin also wants their children, Tabitha and Adam, to be raised as mortals, but understands that witches cannot be banned from using witchcraft - they can only be taught when and when not to use it. He is especially firm with Tabitha because of her headstrong nature.
Darrin first meets Samantha's mother, Endora, who hates mortals, shortly after he and Samantha moved into their new home at 1164 Morning Glory Circle. Endora immediately disapproves of him, questioning why he objects to her daughter being herself. Her father, Maurice, disapproves of "mixed" marriages and has a terrible temper. When he first meets Darrin, he "disintegrates" him with a wave of his hand. Endora and Samantha lose their tempers with Maurice and order him to bring Darrin back. Samantha tells her father she loves Darrin and not to take him away from her, and he finally relents.
