My Peter was born in 1820 and married in 1840.It`s possible the Susan you mentioned could have been his mother but I don`t know. I have read the Ouderkirk family book but my Peter is not mentioned. I contacted the Ouderkirk Society in Atlanta,Ga. but they couldn`t help me either. The story is he went to Calif. for the gold rush. He was in N.J. in the 1850 census but no trace after that.His wifes name was Gertrude Danberry and she died about 1851.
