Russell was born at 50 Queen Street (now Dominic Street) in
Newry,
County Down, the elder son of Arthur Russell (d.1845) of
Killowen,
County Down, a brewer, of Newry and Seafield House, Killowen, County Down, by his wife Margaret Mullin of
Belfast. The family was in moderate circumstances. Charles was one of five children: his three sisters all became
nuns and his brother
Matthew Russell was ordained as a
Jesuit priest. Although Russell believed himself to be of Irish origin, he was later granted for his coat of arms a
differenced version of the arms of the Russell
Dukes of Bedford, which family originated in Dorset, England, in the 16th century. No relationship between the two families is apparent. Arthur Russell having died in 1845, the care of his large family devolved upon their talented mother and their paternal uncle,
Charles William Russell. He studied at the
diocesan seminary,
St Malachy's College,
Belfast, at a private school in
Newry, and
Castleknock College, in
Castleknock,
Dublin. He then entered the law offices of Messrs Denvir, Newry, in 1849, and of O'Rourke, McDonald & Tweed, Belfast, in 1852. Admitted a solicitor in 1854, he practised in the
county courts of
Down and
Antrim, and became at once the champion of the Catholics who had resisted organised attempts at
proselytising by
Protestants in these counties. He matriculated at
Trinity College, Dublin in 1856, but never graduated. ==Lawyer==
