Another victim of typhus in Mayo in 1868 was Patrick McBride, who had come to Westport from Antrim in the 1850s and become a merchant. He died aged 35 when his youngest son, John was a baby. John grew up to become Major John McBride, marry the celebrated beauty, Maud Gonne, be executed after the 1916 Easter Rising and be mentioned in a famous poem by Yeats. An elder son of Patrick McBride was elected as the first Sinn Fein deputy for West Mayo in 1918.
