Frederick jnr getting the estate kind of confirms that he was leading a double life, as the law stationer certainly did not have a son called Frederick with the wife he appears with most often!
I don't suppose you have stumbled over any possible marriages? I have tried so hard to find marriages to a wife called Champion and one called Warner.
And then there is the coincidence of Frederick the law stationer probate to Benjamin Warner who was likely born Bethnal Green, and the mothers maiden name of all the children being Warner, and Harriet the mother being born Bethnal Green.
I don't really believe in such coincidences...….
