Dalziel

Dalziel, Dalzell or Dalyell is a Scottish surname. It is pronounced /diːˈɛl/ ( listen) dee-EL, though pronunciation with a /z/ may be heard outside Scotland.

The unintuitive spelling of the name is due to it being an anglicisation of Gaelic Dail-gheal, meaning bright dale. The sound now spelled with a <y> or <z> is historically a lenited slender /ɡ/, which in Gaelic is pronounced [j] (like English <y>). The English form of the name was originally spelled with a <ȝ> (yogh); this was later replaced with either a <z>, the letter of the modern alphabet which most looks like yogh, or a <y>, which more closely represents the sound.

The name originates from the former barony of Dalzell in Lanarkshire, in the area now occupied by Motherwell. The name Dalzell is first recorded in 1259, and Thomas de Dalzell fought at Bannockburn. The Dalzell lands were forfeited later in the 14th century, but regained through marriage in the 15th. Sir Robert Dalzell was created Lord Dalzell in 1628, and his son was further elevated in the peerage as Earl of Carnwath, in 1639. In 1645 the Dalzell estates were sold to the Hamiltons of Orbiston, who held them until the 20th century.
