Welsh Quakers from North Wales to Pennsylvania - early 18th century

Foulke and Hughes families. Edward Foulke has been very well documented, as he left a memoir of sorts. The Hughes family less so. I am descended from the branch that went to Ontario, Canada after the Revolution. The records of the Quakers of Gwenydd Tpwnship, Pennsylvania (online) have provided a lot of information. Seeking more on the Hughes line in Wales, please.
