"Mrs. McGrath" (also known as "Mrs. McGraw", "My Son Ted", "My Son John", and "The Sergeant and Mrs. McGrath") is an Irish folk song set during the Peninsular War of the early 19th century. Along with "Johnny I Hardly Knew Ye", it is one of the most graphic of all Irish folk songs that deal with sickness and injuries caused by warfare. Irish folk song collector Colm Ó Lochlainn described "Mrs. McGrath" as "known to every true born citizen of Dublin". It was very popular among the Irish Volunteers in the years leading up to the 1916 Rising. Although the song probably dates from the time of the Peninsular Wars between 1807 and 1814, the earliest written account of it in Ireland was in 1876. It is believed to have been popular with soldiers during the American Civil War (1861-1865). The song was recorded by Burl Ives, Tommy Makem, Peg and Bobby Clancy, The Clancy Brothers and others. I learned it from the Clancys.
