Churchill’s Mother, (Last name, Jerome)was either Jewish or half Jewish.

You see that on the Internet a lot, but it's not true. At least, the Jerome family was established in New York going back to the 18th century and were of French origin. The family did claim, though, that they were part Iroquois.

I have read a few biographies of Winston Churchill and do not recall that being mentioned. Not disputing, but did come across this:

Moshe Kohn, in an article in The Jerusalem Post on 15 January 1993, alleged that the Jerome family name was originally Jacobson, and that Jennie's ethnic ancestry was, in fact, Jewish, at least on her father's side. However, there is no truth to this claim; the name of the family has always been Jerome since the family (in the person of a Huguenot immigrant named Timothy Jerome) first set foot in America about 1717.

Again, not disputing but your point may be based on the aforementioned JP article.

What I do recall is that Winston had definite opinions about Islam, none of which were positive.
