This is interesting, I have a Case Briggs, who is the Brother of my GGG Mother Charlotte Briggs whose Father is Thomas Briggs, and mother is Charlotte Case. This Briggs Family had a coal shaft in the Keyser Valley (now part of Scranton, PA) and sold it in the 1840's. Case Briggs signed a Civil War Disability Pension Petition form for another ancestor Judson Wayne Slocum in Lee Township, Franklin County, Iowa about 1881 (don't have the document image in front of me!). Is this the same family, but different branches that named the children in the same manner? This Briggs genealogy is available at the Lackawanna Historical Society as a one page typewritten document dated 1963. I am looking to extend this family tree further into the past.
