I don't have info on any children of George and Mary older than Peter.Other children of George and Mary are (as per a 1880 census extract):
George DAUBERT Self M Male W 46 PA Farmer PA PA Mary DAUBERT Wife M Female W 44 PA Keeping House PA PA Peter DAUBERT Son S Male W 19 PA Works On Farm PA PA Elmer DAUBERT Son S Male W 16 PA At Home PA PA Philip DAUBERT Son S Male W 13 PA At Home PA PA Pheobe DAUBERT Dau S Female W 8 PA PA PA
The birth appears to be very close to what you have for your George Daubert.I don't have any maiden name info on Mary.
I have the following notes (From Peter's record), which you might be able to follow up on.
!Birth: Taken from Census Records for Banks Daubert in 1910 Census in Crawford City, in Crawford Township, Dawes Co., Nebraska.Birth location in PA.
!Notes: Info I had (don't recall source) had Peter married to Sarah E.Father is Peter Daubert? or Daubart?Grandmother Barbara?Great aunt?Found at age 80 in 1850 in their home.Mother is possibly Catharine.
