Hey. There are a few Mullacranes in Gisborne,NZ and palmerston north,NZ.
I, myself have 3 sisters and 1 cousin who is a Mullacrane and also my dad and his sisters. There are no boys to pass the name on unless the palmerston north Mullacrane had sons! Which im not sure. My Dad knows more about him - i just saw him on TV (hes a Sergeant)
Just thought id let you all know that there are more Mullacranes as im not sure there are many left as there are so many girls!
