Hi! Well...to answer your first question, the Baldridge family is so well researched that the John Baldridge(1754-1834)will is found many places on the internet.One is located at Smokykin.com.If you google it, you will find the transcription.
There are so many out there descended from either James Porter & Sarah Patsy Baldridge or Wm Porter & Rebecca J Baldridge, I hope one day there will be proff to link them.To me, all the evidence points to the fact that William and Margaret Porter (and children) of Jefferson Co IL are the same couple from Rutherford Co NC.However, I haven't found absolute proff yet.
I keep hoping someone out there has one piece of evidence out there to make the link with absolute certainty.For example, if there we could find a bible record the stated the either Wm (1820) or James Porter was born in Rutherford Co, NC, that would be enough proff for me.:-)
