Dark Shadows

 

 

Begun in 1966 and continuing until 1971, Dark Shadows was a gothic soap opera that introduced the Collins family and their history that included among things lycanthrope, vampirism, witchcraft, cults, and skullduggery. Dark Shadows established itself as a cult favorite show and remains very much  a part of fandom's history spawning three movies to date and several attempted reboots.

The Dark Shadows Wiki is the definitive source online for all things Dark Shadows and has been an excellent resource on the show and the other versions.

So far I've written up the following:

Angelique Brochard - A powerful witch and occasional enemy/ally to Barnabus and the Collins family.

Barnabus Collins - An ancestor of the current family, cursed with vampirism 

Collinwood - the Collins family home as well as the concept of 'Parallel Time'

Count Andreas Petrofi (and his hand) - An enemy of the Collins family and powerful warlock

David Collins - the youngest of the Collins family with strong psychic powers

Laura Collins  - The presumed dead wife of Roger Collins and mother of David - also a powerful creature called a 'Phoenix'

The Leviathan Cult - an ancient cult that serves primordial masters who seek to control the Collins family, especially Barnabus Collins.

Doctor Julia Hoffman - Physician and scientist who is an ally to Barnabus Collins and the Collins family.

Quentin Collins - An amnesiac member of the Collins family who was both enemy and ally.
