I am looking for information concerning Julia Ann Boileau (Julie Anne?) who married John King in St. James Catherdral in Toronto.

John King, (signed his name with an 'x')Bachelor, of York township and Julia Anne Boileau (signed her name with an 'x'), Spinster, also of York township,were married by Banns, on 7th September 1840 by Rev. Henry James Grasset.
Witnesses were an Isaac ('x') King; Louis Boileau.

and/or her brother Louis who married Hannah King.

I am interested in any information concerning the family.

thank you,
Leah
