There is a James Stewart and John Stewart listed as North Carolina Regulators.
Also, quoted from the same article above:
“William Brown, William Butler, James Copeland, Herman Cox, Samuel Deviney, James Emmerson, John Hartzo, Robert Mateer, Forester Mercer, Benjamin Merrill, Captain Messer, James Pugh, Raleigh Southerland, James Stewart, Robert Thompson were highlighted as of special significance in the movement.“
These are most likely the two brothers listed above that have little to no information on their Wiki profiles, compared to brothers Charles and Matthew.
Familytree YDNA test matches the patriarch of this line [[Stewart-27074|Allan Stewart jnr. (1688-1779)]]. Though a solid paper trial linking our Charles to either James or John remains elusive.
This quote is directly from Charles’ Revolutionary War Pension:
“Question 2nd Have you any record of your age and if so where is it?
Answer. My age was recorded in my father's Bible which was destroyed by the Tories, in the time of the Revolutionary War“
It is my belief that James Stewart was the father of Charles and when Charles was about 9 or ten years old his father participated as a North Carolina Regulator against the Tories and Loyalists. And James’ Bible was destroyed either by itself, or more likely, in wider property damage perhaps even his house being burned down.
Either way, this version of events supports Charles’ testimony and demonstrates why there is such difficulty in finding any record of Charles’ father or mother in the historical record. Family history of this line also supports James’ eagerness to join the Revolutionaries as he and his three brothers had recently emigrated from Abbey, Paisley, Renfrewshire, arriving in 1738 and “settling” in Pennsylvania. This is between to the time of both Jacobite uprisings in Scotland (1715 and 1745). There is little doubt that James and John sided with the Revolutionaries in both Scottish and American conflicts.
James Stewart was pardoned according to this source, for his involvement with the Regulators in 1771 and died about a decade later (probably in Georgia):
The fate of his brother John Stewart remains unknown. He either escaped capture and fled North Carolina to Kentucky or Georgia, or he was killed in the early stages of the American Revolution, as a Regulator. Given that James was considered a leader of the insurrection and John was not captured with his brother, supports the conclusion John was killed early in the conflict.
