My Great Grandmother was Hilda Christopherson, married to Carl Brevig and after his death Robert McCarty. My Grandmother was Velva Mae Brevig. Was your wife's grandmother Ella or Crystal?Or Lorraine or Hilda McCarty ? I would be very interested in finding out more and sharing databases if our families are actually as related as it seems we are. I noticed on the 1930 census report ( South Dakota) that a family by the name of Wold was a neighbor to GG Hilda's family. By any chance your family? Very curiuos. Please email me at a.lg595@gmail.com
