I've been researching the Barneycastles for 10 years, and your family has me completely stumped.I suspect there is a connection but am not sure.The problem is finding old records to support my guesses, and unfortunately the records for your area of NC & SC are sparse.
Is your family the same one that was often called Cassels instead of Cassel(l) when living in Montgomery & Stanley Counties?Where in Eastern NC did Thomas come from?
Here's what I know - the early Barneycastles moved from Accomack VA area to Craven and then Bertie NC in the 1740's.They have many descendants.There was an elusive Thomas Barneycastle born sometime in early 1700's who supposedly lived in Bertie NC, but I have only found one reference to him.
There was a branch of the early family that migrated from Bertie NC to Kershaw, SC, lived there briefly, and eventually ended up in Alabama.A son, John, and daughter Sarah, married their spouses the same day in Mecklenberg, NC, in August 1822.Sarah used the last name Castle, John may have as well.I'm not sure if John stayed in Kershaw SC, he disappears from records and I wonder if that's because he used the name Castle.
So as you can see, there are enough coincidences to make me wonder if your family and ours might be the same one.The only thing that throws a wrench into this theory is the use of the name Cassels instead of Cassel.
Also, there was a Benjamin Cassel who fought in the Civil War, he lived in Cabarrus Co where many Cassels lived.In one of his Civil War receipts, his name is listed as W. Barneycasel.He always used Cassel in official records, so I do believe he's a Barneycastle who changed his name.
In fact, my branch of the family dropped the Barney after the Civil War, and thereafter used Cassel (my maiden name).Msny Barneycastle families dropped either the Barney or the Castle/Cassel part of the name.You wouldn't believe how many variations there are.
Let me know your thoughts on this, I'm interested in your family history.Thanks!
