Caroline's ancestor Sir Hercules Langrishe was well known for good living and good drinking. Once in the 1780s he was said to have drunk three bottles of port in one evening, and a friend asked if he had had any help with them. He replied "None, save that of a bottle of Madeira."
The late eighteenth century Sir Hercules was a member of parliament and a champion of the Irish catholics, up to a point. He supported giving them most of the rights they lacked, such as admission to the universities, but he was not so keen on giving them the vote.
The Langrishes (Caroline's family) were Lords of Ballyhale in County Kilkenny, Ireland, and lived at Knocktopher Abbey, near Kilkenny, from 1679 until 1981. The house is built on the site of a Norman castle and is now a health resort.
Her real break in television came with The Flipside of Dominick Hyde (1980).
Caroline's first screen role was in Frederic Raphael's mini-series The Glittering Prizes (1976).
Caroline's start as an actress was in repertory at the Bristol Old Vic Theatre, in the west of England.
She has two daughters, Leonie and Rosalind.
Caroline was previously married (1984-1996) to the English actor Patrick Drury.
