Eileen Cassells married Ian Richard Kyle Paisley on 13 October 1956. They have five children, a daughter Rhonda (a graduate of Bob Jones University, who served as a member of Belfast City Council but has long since left politics), and two further daughters Sharon and Cherith. They also have twin sons, Kyle and Ian (the former a Free Presbyterian minister, the latter a DUP MP).
It was announced on 11 April 2006 that she would be one of the first three members of the DUP to be created a life peer. She was gazetted as Baroness Paisley of St George's, of St George's in the County of Antrim, after the ward that she represented on Belfast City Council, on 14 June 2006, and was introduced to the House of Lords on 3 July 2006. Following her husband's elevation in July 2010, she and her husband now both hold seats in the House of Lords.
Azure three Pallets wavy Argent enfiling five Mural Crowns in cross Or
On either side two Dragons the dexter Argent wings feathered Or the sinister Or wings feathered Argent
CROWNED WITH LOVING KINDNESS
The wavy pallets are a river allusion and are shown enfiling five crowns as a pun on the grantee's maiden name of Cassells. Five is a significant number as the grantee has five children. Dragons refer to St George and have been differenced by membering them with feathered rather than reptilian wings.
