Born in Mayo in 1865. Although he initially trained as a doctor, MacBride abandoned that profession in favour of work with a chemist. He travelled to America in 1896 to further the aims of the I. R. B., thereafter travelling to South Africa where he raised the Irish Transvaal Brigade during the Second Boer War. MacBride married the Irish nationalist Maude Gonne in 1903. He was not a member of the Irish Volunteers, but upon the beginning of the Rising he offered his services to Thomas MacDonagh, and was at Jacob’s biscuit factory when that post was surrendered on Sunday, 30 April 1916. He was executed on 5 May 1916
