The family tale is that the father was a man named John Crombie and that she had in some manner petitioned that he be listed as father. Im not sure if there would be such things as court records.
There is a register of corrected entries attached to his birth certificate.It names his father as John CROMBIE, farm servant, Kinghorn, Newmachar.His mother is recorded as Margaret ROSS, domestic servant, Ross Hall, Newmachar.- dated 20 February 1879; District of Kintone, Aberdeen.
