I have come across the surname BOYD in 2 of my Wilson's

The family that the middle name BOYD 1st comes up in is that of Aaron Wilson br Pa 1816 [father was a William Wilson br Pa and Mary Ann Wilson br Pa 1834 nee Westlake son

William Wilson br 1854 in Springfield Township Mercer Co Pennsylvania

Wm marrried Rachel Elizabeth Campbell br 1853 Butler Co Pennsylvania daughter of James Campbell br 1814 Butler Co Pa and Elizabeth Ann Covert abt 1821 Pennsylvania

Their son WILLIAM BOYD Wilson br 4 Oct 1884 died without issue 27 Sept 1913 Evens City Pennsylvania in a oil field Accident

Then my own father
WILLIAM BOYD Wilson 1923

Son of Herbert Leyman Wilson and Mary Ann Wilson nee Klee of Butler, Butler Co Pennsylvania

Herbert was son of James Aaron Wilson and Elizabeth F Wilson nee Double

James was brother to the 1st WILLIAM BOYD Wilson

My father told me that BOYD was a family name. I have always wondered where it came from in the family. I have never found it in the Campbell side or the Westlake side as of yet.
The Klees were from Germany so that rules them out
