Sam married Sarah Borrow in 1843. She was the daughter of an old friend, William Borrow, who Lane had appointed to a managerial position in the Britannia. On Lane's death in 1871, Sarah, succeeded him as proprietor and manager, and continued until her own death in August 1899. She appeared regularly as principal boy, in the Britannia's annual pantomimes and in the annual benefit night, appearing in a final tableaux as "The Queen of Hoxton". Her name "appeared on . . . playbills as the author of a series of plays translated and adapted from the French." Sarah Lane made her last stage appearance at the Britannia's 1898 Christmas show, aged 76. Large crowds lined the route of her funeral procession from the theatre to Kensal Green Cemetery. Her estate was valued at a quarter of a million pounds, a significant sum in 1889.
