:Polish American means an American citizen of Polish background. Birth in Poland is certainly not necessary. Please do acquaint yourself with the relevant article. Mrs. Gołębiowska clearly identifies as such, and I do believe this is how Americans can be assigned to one of such "ethnic" groups. We are not here to perform OR and try to invent new ways of describing somebody's ethnicity, or try to estimate how much a person is or isn't of particular ethnicity/background.
