I made a poll a few days ago about middle names for [name_f]Clementine[/name_f] (last name [name_m]Ross[/name_m]). [name_f]My[/name_f] DF loves [name_f]Annabelle[/name_f] and since [name_f]Clementine[/name_f] was my pick (he isn’t a fan, but is going along with it) I figure that’s fair. I’m about 90% sold on it.
I’d really like to use my aunts name as a second middle name. Is [name_f]Clementine[/name_f] [name_f]Annabelle[/name_f] [name_f]Iris[/name_f] [name_m]Ross[/name_m] too much?
I don’t think it is too much, but I would switch the placement of [name_f]Iris[/name_f] and [name_f]Annabelle[/name_f] to make it easier to say. That is just my preference. I think it flows better as:
[name_f]Clementine[/name_f] [name_f]Iris[/name_f] [name_f]Annabelle[/name_f] [name_m]Ross[/name_m]
I like the combo, yes. It’s a great compromise, and not too much since [name_f]Iris[/name_f] is pretty short.
I think it’s a lovely combo! Perhaps you can spell it [name_f]Annabel[/name_f] instead of [name_f]Annabelle[/name_f] to make it a bit shorter, but either way I think it’s beautiful 
I agree the flow is a bit better with [name_f]Iris[/name_f] earlier, just because both [name_f]Iris[/name_f] and [name_m]Ross[/name_m] end in S. But your version is fundamentally fine. The name without [name_f]Iris[/name_f] is also fine - initials would spell CAR - which might be good, bad, or neither in your book.
