Surname dilemma

I was looking over my different notes for my book yesterday, and I’ve realised I’ve used two different surnames for the main character in different sets of notes.

The two surnames I’ve been switching between are McIntyre and McIntosh. Which one do you prefer? The mc is called [name_f]Zadie[/name_f], her sisters are [name_f]Hazel[/name_f] and [name_f]Margo[/name_f], and her parents are [name_f]Rona[/name_f] and [name_m]Jack[/name_m], and they should all have the same surname.

Hmm… I like them both, but I slightly prefer the flow of [name_f]Zadie[/name_f] McIntyre.

Another vote for McIntyre but mostly because McIntosh makes me think of the computer.

I vote McIntyre!

McIntyre it is then! Thanks to all of you.
