Baron Skryne was the title of the holder of an Irish feudal barony : it derived from the parish of Skryne, or Skreen, in County Meath. It was not recognised as a barony in the Peerage of Ireland, but was habitually used firstly by the de Feypo family and then by their descendants, the Marwards. The Baron Skryne was not entitled as of right to sit in the Irish House of Lords, although it seems that in practice the holder of the title was often summoned to the Irish Parliament.  The title fell into disuse in the seventeenth century, when the family estates were forfeited to the English Crown.
De Feypo Barons of Skryne
Hugh de Lacy, Lord of Meath in 1170 granted the lands of Skryne and Santry to his lieutenant Adam de Feypo, who was the first of his family to use the title Baron of Skryne. Despite Adam's loyalty to Hugh de Lacy, his son Richard, second Baron Skryne, witnessed a charter in 1210 forfeiting the de Lacy inheritance. A later Richard, perhaps the first Richard's grandson, died in the reign of Edward I leaving an underage son, Simon. In 1302 Simon, by then an adult, brought a successful lawsuit against his former guardian Theobald de Verdon for wasting his inheritance. The last of the de Feypo barons of Skryne, Francis, founded an Augustinian friary and a chantry about 1340.
Marward Barons of Skryne
Francis's daughter and heiress Joanna married Thomas Marward in about 1375, and their descendants also used the title Baron Skryne. When the Marwards first adopted the title is uncertain, but it seems to have been before the 1460s, when Anne Marward, described as the daughter of Baron Skryne, married as his first wife Sir Alexander Plunket (died 1503), a future Lord Chancellor of Ireland. Walter Marward, Baron Skryne (died 1487), who was probably Anne's brother, was apparently a man of some consequence, who married Margaret St Lawrence, daughter of the powerful Anglo-Irish peer and statesman Christopher St Lawrence, 2nd Baron Howth. 
In the sixteenth century the Marward family were involved in two notable scandals. In 1534 James Marward, Baron Skryne, grandson of Walter and Margaret, was murdered by Richard FitzGerald, younger son of Gerald FitzGerald, 8th Earl of Kildare, supposedly at the instigation of James' wife, Maud Darcy, who later married Fitzgerald. James left an only son Thomas (or Walter) who died about 1565, leaving a daughter and heiress, Janet, titular Barones of Skryne. Her mother, Janet Plunket, daughter of Sir John Plunket, remarried the leading judge Nicholas Nugent, who was given wardship of his step-daughter. Nugent apparently allowed his favourite nephew, William Nugent to kidnap Janet and force her into marriage. Despite the scandal surrounding the marriage, it seems that it could not be dissolved.
Forfeiture of the Barony
The Skryne inheritance passed to James Nugent, eldest son of William and Janet, but he forfeited his lands after taking part in the Irish Rebellion of 1641, and the title lapsed.
