I thought it was interesting that two cast members from "DYNASTY" died within a week of each oher (John Forsythe on April 1, Christopher Cazenove on April 6). I did some research and found that a few other cast members died within a month of each other...

Mable King / Shirley Hemphill of "What's Happening" (actually 31 days apart)
Robert Rockwell/Richard Crenna of "Our Miss Brooks" (six days apart)

Any other cast members from a tv show who have died within a month of each other?

Can it be these are the only pairings? I thought for sure there would be more!

Not exactly a TV series (and not quite within the requested time frame), but
Larry Fine (who died on Jan. 24, 1975) and Moe Howard (who died on May 4,
1975), of The Three Stooges, died within about three months of each other.
