Baron Slane

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.

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.

After the title became dormant, 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 had succeeded in 1612.
