My maternal grandfather was John Berrien McMullen born in Hernando county Florida in 1913. His grandfather was John Fain McMullen, one of the seven McMullen brothers born in South Georgia and later died in Perry, Florida. I have heard the folklore of "Eli" and Margaet Nancy Vick. I hired a researcher from Scotland to research this family tree. I had no luck at all. I joined ancestry.com and only found what looks like three james McMullens have been blended into one. One family I found that looks like this could be a clue; Sarah Vick Married a James McMellon in North Carolina and moved to Lowndes county Georgia. Could this be the parents of James and William McMullen?
