Letters to Mary Owen (née Godolphin), wife of William Owen of Brogyntyn, 1730-1784, mainly from her immediate family, Godolphin and Owen relatives, friends and other close associates. They constitute a rich, lively source of information on the personal, domestic and social circumstances of an eighteenth century gentry family. Many of the letters reflect Mrs Owen 's own interests in music, theatre, literature, political news and high society gossip among her contemporaries. Recurrent topics include the ecclesiastical career of Lewis Owen; renovations at Porkington, 1735-1743; the estates of Richard Clayton and Arthur Owen; Elizabeth Longueville 's settlement; Jacobite disturbances; elections in North Wales and Shropshire; church preferments in England and Wales; and court life under the Hanoverian royal family, 1731-1752.

Private letters exchanged between Margaret Godolphin, [c. 1698]-1764, and various members of the Godolphin family of Abertanat, Eton and Thames Ditton, 1698-1763, including her parents, Sydney and Susanna, her sisters, Ellen and Mary, her nephew, Francis, their Hoblyn and Pendarves relatives, and others; together with letters from friends, solicitors and other professionals. The contents reflect in great detail the personal, domestic and social circumstances of an eighteenth century upper class family, against the background of the Jacobite Wars. Recurrent topics include the management of the Abertanat estate, especially the exploitation of timber, the death of Master Henry Godolphin, 1722, physical ailments, financial investments, family settlements and inheritance. The correspondence of Ellen, Margaret and Mary Godolphin from 1728 to 1730 shows a preoccupation with the reluctance of Miss Mary Godolphin to marry William Owen of Porkington!
