Eileen (Ellen) Costello was an English-born Irish politician, writer, teacher and folklorist.

Seanad Éireann was the upper house of the Oireachtas (parliament) of the Irish Free State from 1922 to 1936. It has also been known simply as the Senate, First Seanad, Free State Senate or Free State Seanad. The Seanad was established under the 1922 Constitution of the Irish Free State. A number of constitutional amendments were made to change the manner of its election and its powers. It was eventually abolished in 1936 when it attempted to obstruct constitutional reforms favoured by the government. It sat, like its modern successor, in Leinster House.
