George was the eldest son of Captain Hampden Evans and his wife Margaret née Davis of Portrane, County Dublin.
In June 1834 he was involved in an angry public confrontation with Daniel O'Connell, leader of the Repeal Association.
He was highly critical of what he saw as O'Connell's autocratic leadership style and assumption that he represented all shades of Irish opinion.
He argued that O'Connell was trying to silence the "men of property and education" adding that he would sooner "be doomed to perpetual exile than submit to such a tyranny".
[5][6] In 1844 his widow built a replica of an Irish round tower in his memory, which now stands in the grounds of St Ita's Hospital, Portrane.
