My brothers were not, I was for medical reasons, my grandfather was, I have no idea if my father was or was not. I know 2 nephews were and 3 were not, the others I do not know and I am not about to go asking. I saw one brother in law nude (after a swim at the local YMCA in the showers, nothing sick or sordid) and he clearly was not circumcised, I have no idea about the other one.
