Thank you everyone for the original post and photos and comments and replies. Fascinating reading, you have greatly added to my education.
Here’s some information to add to the ambiance of these fine rifles from "Peden’s of America" by Eleanor M. Hewell (House of David); page 478:
"Thomas [Peden] was born at Fairview, S. C. He was a gun and locksmith by trade and married Nancy, daughter of "That Redoubtable, old Whig rebel, Bill Hanna, who escaped unhung," (Allaire's Diary), one of the heroes of Cowpens, S. C.
"They settled near the old home on the mill tract, later exchanged for a better place on Reedy River, where he built his shops and spent his life. The Peden historian, Miss Eleanor Hewell, recalls this old couple among her earliest memories, standing in great awe of Aunt Nancy, who was a precise house wife with a horror of children. Her hair, which was "ruddy gold," rolled away from her broad brow in a Pompadour of short natural curls. Her caps were snowy white and had no frills the curls forming a natural trimming. Her face was handsome. Dear Uncle Tommy and Aunt Nancy, who was a devoted Methodist, are buried at Fairview.
Their only child, David Thomas Peden was born 1840. He was a gunsmith, and during the War between the States first enlisted as a member of Company E., Hampton Legion, but was sent home in 1863 to engage in the manufacture of ammunition in the Confederate government works at Greenville, S. C. (A few hundred yards from the historian's home stands the site of this once famous "gun factory.") "He was married about 1855 to Lucinda Terry, daughter of Charles and Pamela Terry. To this couple was born one child, a daughter, the mother dying a few weeks after her birth."
Thomas Peden’s birth date is 11 February 1799 and death 20 December 1858 according to “Peden’s of America."
wildcatter wrote about the apprentice David Boyd, he was probably a 1st cousin once removed. "Peden’s of America" pg 375 lists: David Boyd born 23 Feb 1817 died 27 Oct 1890 married 14 Oct 1841 to Mary McDill Peden, (granddaughter of Alexander) born 29 Jun 1823 died 18 Aug 1868.
I am a Peden ancestor from the House of Alexander Peden and David Peden is his youngest brother; both were born in Ireland and immigrated with their family in 1768 to Charleston, SC. Alexander, David, and the 5 other brothers served in the American Revolution and are proven Patriots by DAR and SAR. Their brother James (Thomas’ uncle) was also a gunsmith. So, the gunsmith Thomas Peden (David's son) is my 1st cousin 6 times removed.
I am anxious to wonder the halls of the gun museum at the Chickamauga Battlefield in hopes of discovering another example. I will certainly look at these long rifles differently from now on. Years ago, I bought a replica “Kentuckian” by Armi just to shoot and have fun with. I was surprised and pleased when I compared it to these photos just how accurate it is, down to the curved brass butt plate, but it is only a 36” barrel, 50 cal. While I don’t have a real Peden Rifle, I do have something to show my grandchildren when I tell them about their Peden ancestors.
