MacCarthy's father Hamilton Wright MacCarthy exhibited independent works at the Royal Academy and the British Institution in 1838 and between 1846 and 1867.
They included a number of portrait busts (10-12).
He contributed to the Great Exhibition a group of a deer hunt, consisting of a Scottish huntsman about to blow his horn, with a felled stag and two dogs 'executed in silver for ornamental purposes'.
It was praised as 'a spirited performance, well composed' and was considered 'a credit to the designer'.

His wife exhibited a statuette of a famous racehorse, 'Pyrrhus The First', at the BI in 1857.
Their son, Hamilton P MacCarthy, was also a sculptor and he exhibited portraiture and ideal works at the Royal Academy between 1875 and 1884.

In London, MacCarthy studied with his father, and in Antwerp under Kerckhoven and at the RA Schools in London.
 He also attended St Marylebone School.
At age 39, MacCarthy moved from London, England to Toronto, Ontario, Canada in 1885.
Thirteen years later he moved to Ottawa.
He studied at Royal Canadian Academy of Arts (R.C.A.) and, later, was made a member of Council (1906).
He was also a member of the Ontario Society of Artists (O.S.A.).
His work appears in galleries and public parks throughout Canada.

MacCarthy had 15 children.
The first three were born in England, the others in Canada.
One of his sons Coeur de Lion MacCarthy (1881–1979) also became a sculptor.

Coeur de Lion executed many busts of political figures including the bust of Queen Victoria for the alcove above the Speaker's Chair in the Senate Chamber.
He worked with Dominion carver Cléophas Soucy on the figures for the Parliament Buildings including the lions at the entrance.
MacCarthy set up a studio in Montreal in 1918.
He is well known for his sympathetic memorials for the CPR and the Verdun War Memorial.
