Vicar: A vicar ( ; Latin: "vicarius") is a representative, deputy or substitute; anyone acting "in the person of" or agent for a superior (compare "vicarious" in the sense of "at second hand").  Linguistically, "vicar" is cognate with the English prefix "vice", similarly meaning "deputy".  The title appears in a number of Christian ecclesiastical contexts, but also as an administrative title, or title modifier, in the Roman Empire.  In addition, in the Holy Roman Empire a local representative of the emperor, perhaps an archduke, might be styled "vicar".

A parish was formed for it in 1881 from those of Emmanuel Church, All Saints and St John's and its permanent church completed the following year, with an organ moved from St Matthew's Church, Friday Street.  The church was demolished in 1964 and for two years its congregation worshiped in the Durning Hall Community Centre's chapel until the parish was merged with that of St John's.  A new church was built for the St James' congregation at northern end of St James Road in 1968.

Garryowen, Limerick: Garryowen Irish: "Garraí Eoin" is a neighbourhood in Limerick, Ireland.  The word Garryowen is a transliteration of the Irish Garraí Eoin - "the garden of John" - and relates to the association in the 12th century between St John's Church and the Knights Templar whose house in Limerick was dedicated to John the Baptist.  In medieval times Garryowen was located just outside the Irishtown area of the walled city of Limerick.  The citadel (located in the grounds of St John's Hospital) was the Irishtown's main fortification.  In 1690, it was the scene of a heroic Jacobite defence-the battle of the breach-which was fought nearby during the Williamite War of 1688–91.  The sally port of the original stronghold has been incorporated into the structure of St John's Hospital.  Other parts of the city walls can still be seen within the hospital grounds.  The Citadel remained in use as a military barracks until 1752.  St John's Gate was situated on the main roadway, nearby, but no trace of it now remains.
