However, until July 11, 2025, I doubted that any of the Vaughans "upstream" from Joseph were "my Vaughans."
But, on Friday, July 11, 2025, I discovered eleven autosomal DNA matches to me, on Ancestry.com, which triangulate onto a man named "William Vaughn" (P3VR-XV5), who is, allegedly, Joseph's paternal grandfather.
According to AncestryDNA’s ThruLines tool, eleven autosomal DNA matches to me appear to triangulate onto William Vaughn (born ca. 1710, died ca. 1775), through descendants of at least four or five of his children.* These matches are distributed as follows:
-
Catherine Vaughn (ca. 1750–1836)
• Connie J. Phelps — 9 cM across 1 segment -
James Vaughn (ca. 1745–ca. 1860)
• Sarah Harkness — 55 cM across 4 segments
• Veronica Erikson Williamson — 10 cM across 1 segment
• David Edwards4382 — 24 cM across 2 segments
• William Marsh — 14 cM across 1 segment
• Karen Loftin — 15 cM across 1 segment
• David Martin — 1 cM across 1 segment -
John Benjamin Vaughn (ca. 1760–1868) [may be the same person as John Powell Vaughn]
• Glenda Phillips — 9 cM across 1 segment
• Rick Modisette — 10 cM across 1 segment -
John Powell Vaughn (1762–1842) [may be the same person as John Benjamin Vaughn]
• R.B. [Bozarth?] — 12 cM across 1 segment -
William Vaughn (ca. 1750–1806)
• Steven Maki — 13 cM across 1 segment
While not conclusive on their own, these matches corroborate my alleged descent from William Vaughan, so I will be taking a closer look at traditional genealogical research which may or may not verify my descent from William Vaughn.

* Two of William's sons appear to be named John Benjamin Vaughn and John Powell Vaughn, but, since they appear to have been born only two years apart, yet survived to procreate, they are probably the same person.
