Well, I used to think a lot depended upon the exact spelling of a name, but since researching my family history, I have come to realize/realise that many if not most surnames have changed in spelling numerous times over the years.  My paternal grandmother spelled/spelt her maiden name differently than her brother did. She even had my father's birth certificate corrected to show her spelling vs. yet a third way.  Jameson, Jamison, Jamerson, Jemison, Jimmison, etc.  It's no wonder people are confused.
