I am English, Polish, Italo-Australian, and Ashkenazi but my Ashkenazi family resided in Belarus forever so publicly I state I'm Belarusian because it's easier to be a crypto-mischling (pardon my appropriation of a very racist term) in WASPville than it is to be Ashkenazi and goyim don't even know Belarus exists, let alone that Minsk was something like 50% Jewish at one time.
