As an interesting footnote, the birth records of Sir John A. Macdonald, who was born in Scotland, indicate that he was born on January 10. When he and his family emigrated to Canada his father, Hugh, recorded his birthdate as January 11, so there was some dispute.
Quand sa famille et lui ont émigré au Canada, son père, Hugh, a fait enregistrer son anniversaire de naissance comme étant le 11 janvier, de sorte que les historiens ne s'entendent pas.
