[2] Following a petition from Clanbrassil to Charles II of England for funds to help the restoration work, the King granted permission for the royal coat of arms to be placed above the door of the rebuilt castle.

[1] In March 1674, Lady Clanbrassil is alleged to have convinced her husband to make a new will to ensure that Killyleagh passed to her, and not his cousins, upon his death.

[3] This ran contrary to the entail in the first earl's will and Clanbrassil's mother warned her son against signing a new will, writing to him that he would die within three months if he did so.

[3] However, she had the body disembowelled and quickly buried in Christ Church Cathedral, Dublin, rather than in the family plot in Bangor, County Down.

Lady Clanbrassil also had the new will, which she brought with her to Dublin, quickly proved by solicitors in the city without informing her dead husband's family.
