Have much info on William Kennedy (entire chapters too long for this board), his son James and their respective descendents. If you'd like to give me an email or mention here with names places and dates that you have I can see what I might match up with records I have here.
Key things of note I suppose is that this William came from Scotland and had been married to a Miss Jean Gregg of Maybole, who is the mother of James - and her surname appears often in the family names as a middle name mostly for the women.
His son James married Elizabeth Warren and they had several children, intermingling with the names of Beall (or Beale), Reade, Garrard, Molyneaux, Dameron, Brough and Ball among others.
William Kennedy served in the Revolution (as well as an Indian War or two as I recall from memory) and lived for time in Virginia (charlotte county) where he married his second wife Mary Lindsay was a widow and her birth surname uncertain. They had but one daughter who married Benjamin Beall.
William with his son in law were known as surveyors and William managed to survey much of Kentucky where he ended up on a huge piece of land in Campbell County. The Kennedy's are also widespread in Lincoln County, Mason County up into Ohio near Oxford and Hamilton. Our family has some correspondence from and to William, including his copy of the letter he wrote to his family back home to let them know while he was land rich (and he most definately was) but money poor and could not send for them.
I have many records of the Kennedy family thanks to a distant cousin's scrupulous notes on virtually every descendant of William and James Kennedy up to about the early 1900's.
So I might be of help if you let me know what names you're looking for and I might be able to find other info you need.
