Fortunately, for those of us researching this line, the jury is back and we have a verdict.
The William Hendricks that married Polly Mansfield is indeed from the line that connects to Robert Hendrick who also posted in this thread.
Through dna testing, it has been proven that I am a direct descendant of William Hendricks (and so is Dixie who started this thread). In fact the dna testing has connected us to William's father, Daniel H Hendricks who married Mary Sabina Crouse, William's grandfather, John (little h) Hendricks and William's great grandfather, James Hendricks referred to as James of Crane Creek.
The marriage bond for the marriage of William Hendricks and Polly Clark has permission given from Daniel H to William and from William Clark, the father of Polly Clark. There was a John Clark who I believe to be Polly's brother who was a surety on the marriage bond along with William Hendricks
William Hendricks gave power of attorney to his "venerable father", Daniel Hendricks in Barren County so Daniel could deal with a property issue in William's absense.
William and Polly had moved from Kentucky before October 1822 after the birth of their first two sons. They were next spotted in Mississippi for the birth of their third son, James Daniel.
For the record, all of the times I have found, the William Hendricks that married Polly Clark, always signed documents as Hendricks, not Hendrick. That "s" comes and goes in our line from generation to generation. In fact, before our William, documents signed by Daniel H, John (little h) and James Hendricks of Crane Creek, had the "s".
I have much documentation on this line. and am willing to share.
At one time, I was also positively convinced that my William was the William that married Polly Mansfield, but the dna testing has ruled that out completely. That revelation took the wind out of my sails for about a year, I was so convinced of the Mansfield connection.
I have much documentation which proves the connection between William and his father Daniel H and William and his connection to Polly Clark. If anyone wants to talk about this, you can email me directly at firstname.lastname@example.org
or call me. I don't think we're supposed to post phone numbers on here, but if you call information for Longview, Texas and get the phone number for Eyeglass Repair Shoppe, you can contact me via phone. I'd love to talk to you about this. As I said, I have much documentation and am willing to share.
