Dalzell Dalziel Dal Yl of Derrynoose Armagh

I am looking for the family of William Dalzell (1847-1915) and Ann Tate (-1904) from Derrynoose, Armagh.
I believe they had 7 or 8 children I know a bit about Andrew, Margaret, Sarah Ann, twins Minnie and Emily.
The last 3 immigrated to Canada about 1911. Sarah Ann was to marry J Graham Stewart, If she did; I wonder who arranged the
marriage. Could there have been brothers who came to Canada first and paved the way?
Emily 1889-1928 married James Vance and is buried in Essex On. Minnie married Robert James Mayhew in Toronto, lived
in Winnipeg and 1924 in Smith Falls ON. Andrew remained in Armagh. Margaret probably stayed in Armagh too.
