Hi Paul and Rosalind re my surname.
Spot on, Rosalind. Lots of variations and originating with Habergham (yes, connection with habergeon which I thought was a battle axe but may indeed be chain mail). Still a civil parish called Habersham Eaves in Burnley area so you are right about Lancashire.
Lots of Habershons around Sheffield - my late father born and brought up in Rotherham.
Highest profile Habershon was probably Commander Roy Habershon (not a close relation nor an acquaintance), a senior policeman who led the fight against the Angry Brigade, a 1970s terrorist group.
