Betty Travitsky,
The two sisters Lady Jane Cheyne (née Cavendish) and Elizabeth Egerton (née Cavendish), Countess of Bridgewater, shared not only a common disposition towards piety and towards adoration of their father, William Cavendish (1593-1676), Duke of Newcastle, but also towards literary activities, including poetry and drama — productions which were themselves largely designed for presentation to him, as their literary mentor, and for their immediate family. Although the authorship of some of their writings can be clearly distinguished, others may well have been collaborative, or anthologized without distinction. For this reason it seems best to treat them as a pair and to record their extant manuscripts accordingly.
These include a substantial anthology of poems, written in a somewhat idealistic vein, largely on family matters and occasionally echoing phrases familiar in other poets of the period. Given the number of poems among them addressed to my sweete Sister Brackley
(i.e. to Elizabeth, who married in 1641 John Egerton, who was then styled Viscount Brackley, becoming Earl of Bridgewater in 1649), it seems likely that the great majority of these poems were by Jane, with just a few additions by Elizabeth. It is more than likely, however, that they collaborated over one or possibly both of two dramatic works,
Besides an extant account book of Lady Jane's (*loose papers
she left on her death in 1663. With certain of the copies still containing his handwriting, the extent to which Bridgewater may have subtly doctored and added to these texts, however benign his intentions, has been the subject of more than one modern published discussion.
No comprehensive edition of the extant writings of the two sisters has yet been produced.
