I know a little boy named
Grant Ryland and his father is
Grant so he goes by Ryland. It sounds like a surname or a combo of
Roland and Rylan/Ryan/Riley, like you mentioned. I don't care for surname-y names that aren't established as given names (and 'only recently' doesn't really count, IMO) nor most names that end in -land, even if they aren't place names.
BTW, your sig is a little distracting because in the world of the Internet, all caps = yelling. :-/
