As I was sitting and waiting for my oil change today, I decided to look up on my "pocket brain"/cell phone, a picture of "John Vaughn Kentucky 1800s".  Forget the pics!  Lo, I came across this website.  And, wow, what a site this is...a goldmine of information from YEARS of research.  It travels down a path of a very distant cousin, however, starts with a very familiar Benjamin Vaughn from Virginia.  He's at the top of the charts on our tree, so you can assume my excitement.  We're talking birth date of 1747 in Charlotte, Virginia.

The author of this website mentions Benjamin's spouses like this:
" Benjamin Vaughn was born abt. 1747, and died unknown. He married (1) unknown. He married (2) Betsey Fra(e)nch Nov. 30, 1808 in Livingston Co., KY."
I had seen through someone else's public family tree that Benjamin was married to "Cherokee".  This could be his 1st wife and Betsey his 2nd?  Adding this to the tree.

The author of this website mentions son(s) of Benjamin Vaughn like this:
"Benjamin Vaughn and his sons, Thomas, Joseph, and perhaps John, all came to Kentucky about 1797. William, another son stayed in Rutherford Co., and about 1807 Benjamin went back and sold the land.
Benjamin and William went back to Kentucky where Benjamin had property."

On my initial search up the Vaughn tree, I started with Aunt Linda's top of the tree...a John W. Vaughn.  I found that his daddy was William T. Vaughn from a public family tree constructed by someone on Ancestry.com.  It's hard to say if from this new info if "Thomas Vaughn" and the "William T. Vaughn" that I actually have record of as being the son of Benjamin are one and the same.  I would assume that the "T" as William's middle name is Thomas but from the quote above it definitely appears as two separate individuals.  Now, also, I can add these other siblings to the tree:  Joseph, "perhaps" John, and William.

The plot thickens!  The name "Pullum or Pulliam" has appeared on this website!  Just as I suspected from an earlier post.  Check it out:
"The Vaughn's,  Wood's, French, Pullam/Pulliam and Lamb's all lived in the same area.  The area where they lived was claimed by both North and South Carolina. So you will find some records in Spartanburg Co., South Carolina and some in Rutherford Co., North Carolina."

This website also suggest that William Vaughn had daughter(s).  I only have one child listed and that is John Vaughn Jr.:  " Ann Wood and her son, Spencer, and perhaps her husband came to Livingston Co. KY about the same time as the Vaughns. Later, when Benjamin left Caldwell County, he sold or gave the land he had to Ann and her son Spencer and to William Vaughn who remained in Caldwell County. Spencer Wood wrote a consent for William Vaughan for one of his (William Vaughn's) daughters to marry. A couple of other Woods men came to Caldwell who have the same names as John Wood's sons."

Other interesting facts about Benjamin Vaughn from the website:

So going down the rabbit hole, it appears that there was some love happening between half siblings, when talking about Benjamin's son, Joseph's children:
