A Hebrew is a Jew, ethnically speaking - which means to be a descendant of Abraham: http://www.scripturessay.com/are-the-jews-a-race-or-religion-define-jew-hebrew-israelites/
So what don't you understand, about being misled to believe someone was:
A - English by birth (which was claimed of him, iirc), not a Hebrew or a Jew.
B - A Roman Catholic.
His Jewish birth was deliberately hidden from everyone, and he was made-up/claimed to be English by birth? Why?
Misled to believe bullshit, yet again. And surprise, surprise. It's by the powers-that-be. Maybe he was an undercover informant.
He was not Hebrew or Jewish by birth, in any sense. This is completely made up.
And who would he be informing to? Israel, which didn't exist yet??
