Hello Denise, I am also a Carlton by marriage.Trying to do a little research on them myself.Mine came into the US in the early 1900's.I believe from Ireland.My William John Carlton came to NY and settled in the Lowell,Boston,MA area. Go to this sight http://bethg.shutdown.com.yell, I was just there,doing some looking for family on my childrens dads side of the family.It's a wonderful sight,lots of information.I hope you find what you need there.There was a couple of Carltons in the area,can't remember their names though. Good luck, Loretta
