General Daniel Morgan 1736-1802 was of Welsh decent. He lived in Winchester, Virginia and died there as well. His home still exist there. I have been to all three. During the last couple of years of his life, he found religion. His minister was Rev. William Hill. 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.
Please tell me where I can see the original pension record you cite.
There may have been a Daniel Morgan from Ireland who lived at the same time in history, but it wasn't, in my opinion, General Daniel Morgan of Saratoga and Cowpens fame. Obviously, you are entitled to believe what you like. There were at least two other Daniel Morgans from Virginia that fought in the Revolution.
I put my faith in his family documents, the memoirs of Rev Hill and the writings of James Graham, who was married to his g grandaughter and wrote "Life of General Daniel Morgan of the Virginia Line of the Army of the United States". There was no reason for these folks, particularly Rev Hill, Gen Morgan's minister who was with him at the time he died, to make this stuff up.
In the absence of anything that actually documents something to the contrary, as an educated historian, I weight these personal statements, (particularly the Rev Hill statements, since he was a historical contemporary of Morgan and a potentially reliable witness)very heavily. Just my 2 cents.
