The McKinneys and Berrys of Missouri

We continue to search for information about our family, particularly need information about McKinneys and Berrys who may have served in the Revolutionary War. And, of course, any information about John Cullen McKinney, Isle of Skye, Scotland, and his ancestors. The Berry family information is very sketchy and we would like any information about them, dating back to Virginia in the late 1700s and before.
