As this is Usenet then nothing is ever going to qualify as "all" (unless
it's something like "all of Queen Victoria's children are dead").

Until the demise of Carl XVI Gustaf, at which point there will be at
least two alive (unless something bad happens in the mean time).

Did they exhume the Queen in 1946 so she could give birth posthumously?
