Barth sisters

When my grandfather was born in 1867, his mother was an unmarried servant in the household of a clergyman, who had two small daughters. The 1900 census shows the daughters unmarried, still residing with their elderly father. I would be interested in translations of their descriptions in that census: Fredrikke Barth -"Syg, kan intet bestille"; Anna Barth: "Bogholder og Kasserer ved Nationaltheatrets kontor Xania".
