As far as where Daniel Morgan was born, all we have are statements made by him to Rev. Hill and statements by his family. Rev Hill kept very good notes regarding the conversations he and the General had. It is well documented that Gen Daniel Morgan told him that he was Welsh and that his parents emigrated from Wales between 1720 and 1730 and first settled in Pennsylvania before moving across the Delaware River into New Jersey. The following is a direct quote from James Graham who was married to Daniel's great grandaughter:
"General Morgan was of Welsh extraction. Between the years of 1720 and 1730, many emigrants from Wales arrived at Philadelphia, and, proceeding thence up the Delaware, settled on its banks. among those emigrants were his parents. He was frequently heard to declare that his father and mother were Welsh and that they had emigrated to this country about the above mentioned period. It appears that after residing on the Pennsylvania side of the Delaware for a year or two, they removed to the opposite shore, in New Jersey, where they lived in a small clearing, cultivated by the father, until all trace of them is lost........."
These statements were made by his known family and confirmed in the writings of Rev. Hill. I have seen the original documents hand written by Hill. Hill also delived General Morgan's eulogy. I have a copy of that hand written document also.
I have written here before that Daniel Boone's son Nathan told Lyman Draper in a personal interview that his father (Daniel Boone) told him that he and Daniel Morgan were cousins. True? Who knows? I believe that they were likely some type of cousin but not necessarily first cousins. Just my opinion and giving some benefit of the doubt to Nathan Boone who claims his father told him this.
As I have said before,DNA may be the only way to resolve all of the speculation regarding this man and his extended family.
