I am from the same line. John Chadwick born in 1713 in Monmouth, NJ, is my 7th great grandfather. Then my line goes through his son John-William-William-James Madison-James Albert. I have done very little work on family to the "sides" as it becomes way too massive an undertaking. Most branches of my family "went forth and multiplied".
I would suggest checking the Family Trees on the ancestry site. Most of what I know is out there. Is there something specific I can help you with?
