Bewitched was always a little vague on what order all of Samantha's Aunts and Uncles came in.
I guess Aunt Clara was the oldest followed by Endora and that Uncle Arthur was the youngest. Where did Aunt Hagatha and Aunt Enchantra fit in?
Just curious if anyone knows this

Endora said she was an only child until her baby brother (Uncle Arthur) was born, so that puts Aunt Clara as Maurice's older sister, I think. Also, Maurice acts very "brotherly" to Clara, Enchantra, and Hagatha whenever they were around. So I guess they were siblings, and judging by looks and attitudes, Clara was the oldest, followed by Enchantra, then Maurice or Hagatha, then one of Serena's parents- who probably ran off to join a commune or something. :happyface
