I just found Gabriel Acker and his family buried in Oakdale Cemetery in Urbana, Ohio. This family lived in Sidney Twp, Hastings County, Ontario. Gabriel's father Jacob Acker had married Rebekah Chrysdale and he is buried in Hogle Cemetery. Jacob Acker was from Dutchess County, New York. He was a son of Johannes Adam Acker born 1751 who married Mary Brill and resided in Brighton, near Cobourg, Ontario.
