On the Cameron County Site; I found an excerpt of JH Beers
book McKean, Elk, Cameron & Potter Counties.
Robert Barr married Catherine Smith b. abt. 1790 White Deer Valley d/o Benjamin Smith & Mary Wilson.
Catherine is a Smith family name, Catherine Smith or Widow Smith lived in White Deer (Mills), bore rifles for the Revolution & was the mother of 10 children.
I think that Benjamin Smith was one of her 10 children OR a nephew of her late husband. Peter's brothers were: Jacob (never married), Daniel, & Michael.
If anyone would share any info, I will share what info I have. Thank You All in advance for anything ~ nothing is trivial!
