Quentin,
Quinten and
Quinton I kinda prefer to
Quintin (something about the 2 Is doesn't do it for me), but I generally like it.
I personally would pair it w/ Jpns. names, but it's too late at night to think about pairs right now, so if you want Jpns. names to pair it w/ let me know and I can maybe do some of that tomorrow... Could maybe try some western ones too...
Matthew or
Mateo may be some to start with.
