V.good, but I saw the Perkin group straight away - if I didn't know that, I'd have got nowhere. Edward VI confused me, but after that, the two groups were obvious.

Oh very good. I too saw Perkin and A.N. Other but was led as[h]tray, even blind to Mary. Congratulations well done.

@St John is Mary I ok there? Tried to be careful about answers that can be swapped. I don't think she can fit in the other group.

Meant to write that as a question @ Malcontent and St John, but started typing in the name box first - didn't notice I'd not corrected the name until I'd posted.

@Midge - it works perfectly well as far as I am concerned. I assumed the nationalities but that is the beauty of a being a puzzle setter, one can throw curve balls. It works when the player realises they have been duped, yet, find it pleasing and rewarding.

@St John - I thought Edward VI was the curve ball for that group because he existed as an actual monarch later.
