Have you seen this website? http://www.butterworths-int.co.uk/ Apparently every Butterworth in the world can be traced back to a small village between Oldham and Rochdale, now called Newhey. I was at an old burial site in Ogden and there were do many Butterworths there.

From "My Chesney Roots"..William Butterworths wife was Ann Whitehead...but no more info to track William and George in New Jersey....I remember when on Conference in the USA in the late 90's a lady came and talked to me said she was a Butterworth from New Jersey...( her maiden name) and we were probably distant cousins...she now lives in Texas and I cannot remember her married Name...Bob your Great Uncle Ed fromSt Thomas had information on relatives in England...Darlene tried to obatin from their daughter ( now deceased) and even tried their daughter....but no luck due to lack of interest....Good Luck on your search...
