I'm not sure exactly what your problem is. If your ancestor is definitely a Revolutionary War soldier, I'd think you'd be able to join the project and at least contribute to straightening out the problem. By the time you get back to the Rev War there are usually hundreds if not thousands of "cousins" and it's necessary to get some sort of consensus of what a soldier's profile should look line and what connections have been proved. The profile didn't look too sourced yet, so it probably needs some more things which will show (or not) that the claimed parents are not likely to be Stephen's parents. the big thing is to make sure not to get in too much of a hurry and present your case to the people in the project so that your position is known and appreciated. Good Luck.
