Lillah, Lady Keeble OBE (born Lila Emma McCarthy; 22 September 1875 – 15 April 1960) was an English actress and theatrical manager.

[5][7] She was directed by William Poel, the theatre manager and Elizabethan specialist, at the Shakespeare Reading Society at St. George's Hall, Langham Place.

George Bernard Shaw was in the audience and noted that "her Lady Macbeth was a highly promising performance, and that some years of hard work would make her a valuable recruit to the London stage".

The following January McCarthy received an offer from Wilson Barrett to join his company for the part of Berenis, in the London production of his play The Sign of the Cross, at the Lyric Theatre.

In Melbourne she appeared as Serena in Claudian; as Auntie Nan in The Manxman; as Gertrude in Hamlet; and as Servia in Virginius, alongside her brother Daniel and with Barrett in the lead role in all four.

McCarthy wrote in her memoir that "British soldiers were eager to adore us – any or all of us […] In Capetown a major sat upon my balcony and said, now that he was free from duty, he would take me to settle upon a chicken-farm in Ireland.

In her memoir she recalls Then one day brother Dan … looks up from the paper he is reading in the sitting-room of our lodgings, and exclaims "Your red-headed man has written a play."

McCarthy played this role in Man and Superman at the Court Theatre, Sloane Square in May 1905,[13] followed by Nora in Shaw's John Bull's Other Island in September.

Her appearances included Shaw's Don Juan in Hell; Alfred Sutro's The Barrier: a revival of Arms and the Man;[16] and, importantly, Euripides' Bacchae.

[17] In 1910, while staying with H. G. Wells and his wife in Sandgate, McCarthy received a letter from a friend who had seen and was much taken with a play by the Norwegian Hans Wiers-Jenssen called Anne Pedersdotter.

The Prime Minister's wife, Margot Asquith, wrote the next day to tell McCarthy how much the King and Queen had enjoyed her performance, "laughing and clapping the whole time".

Inevitably, this led to divorce in 1917–18, and Granville-Barker (now with a hyphen) married Helen Gates (formerly Huntington) at the King's Weigh House Chapel, London on 31 July 1918.

She played the lead in Shaw's Annajanska, the Wild Grand Duchess, dressed at one point in the uniform of the 1st Panjandrum Hussars and wielding a revolver.

[citation needed] Two year later McCarthy met Frederick Keeble, FRS at the Stoke Poges golf club, where they were both members.
