I often read between the lines and am wrong . I am seeing something here in the timeline and story of Benjamin . Usually someone does not change their ideologies unless life jolts . I tend to think his time back in England might have been a bit of a jolt . Dealing with a feudal system of social casting and coming to understand why Josiah needed to leave . There was a wealthy business man and the aristocrats wanted to know about his bloodline as they were in that mentality at the time . I am sure Ben may have suffered some humiliation and such over the subject .
I know what little exposure that I have had with those groups . Everyone walks in the door and the next question is where did you get your wealth and who are your ancestors . I have heard this myself and took note . Some old outdated thinking that wealth and bloodlines must run the same route . But Benjamin having been in America the son of a soap maker and candlemaker was used to be treated with respect I am sure .. and adoration in many cases as being a son of a respected member of that community . So I think this time in England was a jolt to brought him to enlightenment on the dregs of social and biological casting .
The Age where they woke up to the ills of the Divine Right of Kings .
I think they were getting long before that ... in part that is what the Revolution was all about . It may have seems cruel for Benjamin Franklin to have his son thrown in jail for being a threat against Liberty ... but oddly I understand what he was trying to do . He was trying to get William to understand why he needed that constitutional protection . But apparently William did not get the message .
Josiah Franklin came across as such an affectionate father, didn't he? Makes Ben's genius seem less unlikely.
From http://www.ushistory.org/franklin/info/index.htm
Franklin died on April 17, 1790 at the age of 84. 20,000 people attended the funeral of the man who was called, "the harmonious human multitude."
His electric personality, however, still lights the world.
Looks like there might be some genealogical material here
