M is for Mary I,
O is for William of Orange,
N is for the House of Normandy,
A is for Queen Anne,
R is for War of the Roses,
C is for Charles I - the man who nearly destroyed the monarchy,
H is for Henrys I - VIII,
Y is for HenryVI - the youngest monarch ever to succeed to the English throne.
So yes, it is.
Is it possible I've confused an anachronism with an acronym? Or an acrostic?
