I've spent some time thinking about this before, and it provides a clue about the writers accent. For example:
"An 'H'", and "a 'H'" are both equally valid following this rule (by my interpretation), depending on how you pronounce the letter 'H'.
"I think it's mostly Irish with the former."
Actually, it's a shibboleth. It used to be said in Ireland that Roman Catholic called it "haitch" and Protestants called it "aitch". "Haitch" is to be found furth of Ireland though.
