ajstewart on Family Tree Circles

I am researching my family in Newfoundland. Of the following facts I am sure:
I, Amanda Jane Stewart, was born in Halifax, Nova Scotia in 1979
my father, Ernest Fredrick Stewart, was born in Halifax, Nova Scotia in 1952
my grandfather, Ernest John Stewart, was born in Boxey, Newfoundland in 1917
my great grandfather, John Thomas Stewart, was born in Langue de Cerf, Newfoundland in 1867
my great great grandfather Thomas Stewart was born in Miller's Passage, Newfoundland (between 1845 and 1850 there are still some discrepencies)
His parents were William Stewart and Susan, possibly Ridgely. Please let me know if you can help shed some light on this
