Always interested in any possible match with another Butler, are you aware of this site http://www.worldfamilies.net/surnames/butler/results
it may give you some pointers as to the origins of your Butlers. If you send me a private message via Ancestry along with your email address we can compare DNA. Even if you don't match me I have other contacts. In the 10 years since having my DNA tested I have 2 close YDNA matches with other Butlers and a number of close YDNA matches with people bearing the surname Whitson in the USA, it seems the Butler DNA has crept into the Whitson line back a couple of hundred years or so.
Look forward to hearing from you,
