Baron Slane
Baron Slane was a title in the Peerage of Ireland. It was created in 1370 for the Fleming family but forfeited in 1691. Origins. The Flemings of Slane descend from Erchenbald, otherwise referred to as "Archembald le Fleming", of Bratton Fleming, Devon, who was alive in 1087. Archembald derived his surname due to his birth in Flanders, and came to England during the reign of William I. He was succeeded by his son, Stephen (fl. 1145), whose son, Archembald, arrived in Ireland with Henry II in 1171 and participated in Hugh de Lacy's plantation of the Kingdom  of Mide. On the west side of the hill of Slane there are the remains of a 12th-century motte and bailey which was the settlement, destroyed by the Irish in 1176. Succeeding Flemings were Stephen, (died –1214) and Baldwin (died 1260). Baldwin's son, Richard, is the first of whom some substantial information exists. He married Mary/Maria Martin, daughter of Sir Nicholas FitzMartin the Younger (died 1260). Richard died in 1301, but it is unknown when his wife died. Their son, Baldwin (died 1335), married Matilda/Maude de Genville, daughter of Sir Simon de Genville of Trim. They  were the parents of Simon Fleming, 1st Baron Slane, who died on 13 September 1370. An unusual feature of the title was the ability of the holder to petition the Crown to transfer it: after the death of the 12th Baron in 1625, the 13th Baron successfully petitioned the Crown to transfer the title to his younger brother, since as a Roman Catholic priest he did not expect to live on or manage the family estate. He later became Roman Catholic Archbishop of Dublin. Peerage Case, 1835. In the case "Slane Peerage case" brought before the House of Lords in  1835, evidence was submitted by the agent of the petitioner. New creation. The 17th Baron, Christopher, was attainted in 1691 for fighting against William III. The title became dormant after the death of the 19th Baron in 1771, but claimants from junior lines continued to advance their claims into the 19th century. One such was James Ellis Fleming of Tuam, County Galway, who, in 1824, claimed descent from John, third son of Christoper, who succeeded in 1612. The title remains dormant.
