Baron Percy

The title Baron Percy has been created several times in the Peerage of England. The first, soon after 1066, a feudal barony rather than a barony by writ, which continued in parallel with the later baronies by writ, until the abolition of feudal tenure by the Tenures Abolition Act 1660. The second, created by writ in 1299, became extinct in 1517. The third, created by writ in 1557, became extinct in 1670. The present creation was in 1722, by writ of summons.
