My GGGrandfather's middle name was Sudam or Suydam. George Sudam Davis. There was a longstanding tradition in my family of using the mother's maiden name as the middle name of the eldest son. His mother was named Nancy Sudam or Suydam (there are at least 2 spellings in the records). He died in Elba Township in September, 1892. There were at least two other George Davises in Gratiot County in the 1870-1900 period. I can provide census info on the other Georges, if you would like it.
