By now you've learned what I discovered when I went through the messages posted to Genealogy.com and replied to several: NOBODY'S READING THIS STUFF ANYMORE!
I guess people post messages, then, when they don't get an immediate response, they never check back.I did get a reply from one of the other Mark McKinnisses listed, but my attempts to keep in touch did not meet with success.However, another distant relative who coincidentally knew my first cousin in Ohio did contact me and we have become electronic pen-pals of a sort.
Perhaps you are aware that, while there's no reason to doubt the family history of Charles McKinniss coming to America with General Braddock as a grenadier, being wounded in the battle of Fort Duquesne and going on to help settle the Ohio Valley, neither is there any historical confirmation of the story.A contemporary list of the soldiers in Braddock's command does not bear the name McKinniss or anything reasonably close.This, of course, is not dispositive, since record-keeping was not the best in those days and there are a number of reasons why CM may not have been on that list.
My electronic pen-pal, George McKinniss, is investigating whether or not CM may have been with another British general who helped conduct the French and Indian Wars, General Bouquet.Personally, I consider this unlikely.As I said before, there is no reason to doubt the family history, which is rife with details.In addition to that found in the 1905 genealogy compiled by my great-grandfather and others of his generation, there are some orally passed down details such as: after CM was wounded in the leg, one of the treatments consisted of taking a silver silk scarf and passing it throught the wound because they had a strong belief in the healing properties of the color silver.
There are also stories about the blond-haired son of one of the McKinniss settlers who was a favorite of the Indians.The family grew so worried about this that they would hide the boy under an over-turned cooking pot when the Indians stopped by, for fear they would kidnap the child.
Anyway, some of this stuff may be apocryphal, but until we learn otherwise I'm willing to take it on faith!
Must get back to work.Good luck in your pursuits and keep in touch.
