:::::See that's the kind of argument that completely goes against WP:V, because you're using a quote that a person is not an expert in answering her answer is not verifiable. You're right that the reference isn't explicit in saying her father is Jewish, but there are other sources that are more explicit  for instance where it says Her father is Jewish or ; which makes her ethnically at least Half-Jewish whether or not she believes or states she is. I don't know of any situation where "Half-Jewish" is an acceptable term because as far as I am aware not being ethnically, socially, or religiously a Jew makes one a Gentile there are no half measures. This fact is verifiable where her statement is not.
