What was the daughter of the Addams family called in the 1960s TV show?

The Addams Family is an American macabre/black comedy sitcom based on Charles Addams's New Yorker cartoons. The Addams family is a close-knit extended family with decidedly macabre interests and supernatural abilities, though no explanation for their powers is explicitly given in the series. The wealthy, endlessly enthusiastic Gomez Addams is madly in love with his refined wife, Morticia. Along with their daughter Wednesday, their son Pugsley, Uncle Fester, and Grandmama, they reside at 0001 Cemetery Lane in an ornate, gloomy, Second Empire-style mansion.
