Cloudy Jewel by HILL, Grace Livingston

Julia Cloud, the oldest--and most responsible--child of her family, helped raise her four siblings due to their mothers long-time illness and fathers death. After faithfully nursing two ill brothers (who died), she then cared for her invalid mother for many years. When Julias mother passes on, her only surviving sibling Ellen fully expects--and nearly demands--that her spinster sister come live with her family. But to earn her keep, Julia must be their live-in housekeeper and babysitter for Ellens four children. But Julias college-age niece and nephew arrive unexpectedly from California and offer Aunt Cloudy Jewel a surprise opportunity she never expected in her wildest dreams. (Summary by Joy Easton)
