It is the name of my cousin's cat so I think of him :)
I really like it as a pet's name but do think it has a distinguished older man feel to it. (I have seen Rollin too and I hate that)
I think it is usable. It falls in a class with
Simon,
Percy,
Alistair,
Charles.
I like your combos with
Roland as a first name better than as a middle name.
