My Dear Patrick (Cousin, O’Donovan, Mason and Builder, Waterford),

The start of the letter concerns the O’Donovan family in South Kilkenny.

This period had any son named Edmond. He had Daniel, Teige, Murragh, Donagh, Dermod, Richard, and Keadagh. Now I cannot get it out of my head but that our ancestors was one of these seven sons and I would not be surprised if he were Richard the sixth son. But then I have been since I was born that Edmond was the name our ancestors who fled from the County of Cork for the killing of O’Sullivan! This is the great puzzle to me I cannot find any Edmund at all!

Her words are: Signed and sealed.

A.D. 1665

May it please your Grace,

‘The bearer Daniel O’Donovan, son and heir to Daniel O’Donovan, late of Castle Donovan, in the County of Cork, hath been left without any provision for him in the Act of Settlement, which I believe, hath been occasioned, by the death of my Dear Lord and husband and sons, for he spoke claim of Daniel O’Donovan to be a person who at all times and upon such occasions, was ready to serve his Majesty as appears by your Grace to peruse together with his Majesties Gracious letters which he also hath wherein there is mention made of his father’s raising men under your Grace’s command two companies of foot, wherein both his brothers were Captains, and one of them slain with your Grace at the Siege of Dublin at Rathmines, and the other in his Majesties service beyond seas. Now I humbly refer the condition of the poor gentleman to your Grace’s consideration he having no other friends to mediate for him since the death of my dearest friends.
