Why did Christina rossetti use a pseudonym?

Christina Rossetti used a pseudonym, "Ellen Alleyne," primarily to maintain privacy and distance from her personal life and family connections, particularly her association with the Pre-Raphaelite Brotherhood, of which her brother Dante Gabriel Rossetti was a prominent member. By adopting a pseudonym, she could navigate the literary world while avoiding the constraints and expectations that came with her family's reputation. This choice also allowed her to explore themes and styles in her poetry without the pressure of being directly associated with her identity.
