Alice [Makai]
PC-98 Alice is from Makai but Windows canon is actually unknown (unless you believe DiPP Alice theory).
However, according to ZUN, the PC-98 canon has been swept clean and that there is absolutely no connection in terms of story, thus leaving it unclear as to exactly whether the Alice of PC-98 and the present Alice are the same person and how her canon would reflect this. Although it is unclear, this is all ZUN has said.
But otherwise, yes, just by her name and surname, in the Windows canon, we know that she's not from Gensokyo but, otherwise, we don't know.
