Bosworth and Naseby Join Harold in Highbury

I recently noticed that three houses in Elwood Street, near Arsenal's old Highbury ground have some intriguing embellishments.

They have shields and faces of knights around the doors. And above the square bay windows are the names NASEBY, BOSWORTH and HAROLD.

The cartouche between the doors reads FCH which may be the initials of the developer who constructed these three properties

Note the castellations along the roof edges (pic from Google streeview)

I can only assume that the developer at the time (late Victorian?) was a history buff. Perhaps he was trying to commemorate some of England's most famous battles, but why show the locations of Naseby and Bosworth yet not have  Hastings/Battle on the last one rather than the name of the king who died there?
Any ideas anyone?
