Her niece was Gertrude Coghlan. Rose went to America in 1871 as part of Lydia Thompson's troupe touring the U.S.. She made her Broadway debut in 1872 in a musical. Coghlan was again in England from 1873 to 1877, playing with Barry Sullivan, and then returned to America. She became prominent as Countess Zicka in Diplomacy, and Stephanie in Forget-me-not. She was at Wallack's almost continuously until 1888, and subsequently appeared in melodrama in parts like the title-role of The Sporting Duchess.
