Nancy: I have been tracking dozens of John Adams - mostly in South Jersey, but only have dates on about half of them. I do have a John Adams (b. 12/15/1784), son of Jacob Adams (b. 1/16/1758)who emigrated to Burlington County, New Jersey from Germany. John's wife was Nancy (lnu). I only show one son to John, Jacob Adams (b. 1827). The date would be about right for your Adams daughter. However, I know of no West Virginia Connection.
I recently found a HUGE family tree of Wolphert Gerretse Van Kouwenhoven on the internet. It listed over 500 Adams connections (all related to my Jeremy (or Jeremiah) Adams (b. 1604)line on freepages.genealogy.rootsweb.com. It was well indexed. Good luck. Peter Fritz
