Catherine Power's brothers were Henry Brockholst Livingston (1819-1892) and Jasper Hall Livingston (1815-1900), who was her twin. Jasper married Matilda Anne Cecila Morris, the youngest daughter of Sir John Morris, 2nd Baronet of Clasemont and died in England. Henry married Marian Magdalen Gribaldo in Florence, Italy and is buried in the Swiss Protestant Cemetery of Florence.
