I never knew, till learning just recently, that actress Marie Blake, who portrayed Grandma Addams in this series, was the older sister of singing '30s and '40s major screen star Jeanette MacDonald.
Marie's original name was Edith Marie Blossom MacDonald. Blossom Rock was the name that Marie, in her personal life, was most known by, as Blossom was the name she had gone by since I believe childhood, and Rock was her marriage last name. Therefore, by the time of The Addams Family, Blossom Rock was the name (and it was her real-life name) she chose to be credited as. Meanwhile, Marie Blake had been her professional name throughout the majority of her acting career, which is why that's the name she's primarily listed under on TMDb and IMDb.
At any rate, I never would have guessed that Marie/Blossom was Jeanette MacDonald's sister, as there was no real resemblance, and the two women were entirely different types. Plus the names situation, of Marie/Blossom never having professionally gone by the last name MacDonald, further throws one off the scent.

That makes three Blossoms that I know of.
1) Blossom Rock
2) Blossom from the 1990s sitcom Blossom, played by Mayim Bialik
3) And the unique jazz vocalist Blossom Dearie
Another interesting Adams Family cast member is Felix Silla who played Cousin It, as well as a Star Wars Ewok (the one in the glider) and the robot Twikie in Buck Rodgers in the 25th Century

I think Blossom Rock is a cool-sounding name. That could be a great professional name for some present-day star.

It might be a coincidence, but I noticed that both sisters died on the same day: January 14.
