Matthew Peter D'Arcy (18 June 1821 – 28 November 1889) was an Irish Liberal politician.
D'Arcy was the son of John and Eliza (née Selgrave) D'Arcy. After receiving a MA from Trinity College, Dublin,[1] he first married Emma Knaresborough, daughter of William and Maria (née Corballis) Knaresborough in 1853, and they had three children: John Francis Aloysius (1854–1874); William Matthew Joseph (born 1855); and James Frederick Herbert (1857–1918).
After Emma's death in 1858, he remarried to Christina Margaret Daly, daughter of James Peter and Margaret (née Dolphin) Daly, in 1860. Before they divorced in 1887, they had six children: Emma Teresa Mary; Mary Louisa Christina; Margaret Rita Mary (1861–1915); Eliza Mary (1863–1926); Christina Mary (1867–1931); and Matthew Stephen Rodolph (1868–1901).[2]
D'Arcy was elected at the 1868 general election as one of the two Members of Parliament (MPs) for County Wexford. He held the seat until 1874 when he stood down.[3] [2]
D'Arcy was also a Justice of the Peace and a Deputy Lieutenant and, in 1872, a High Sheriff of Dublin City.[2]
