However, the Department of Genealogy in Saint Petersburg said that he was entitled to claim to be a member of the nobility. Markievicz was married, though separated, at the time that they met, but his wife died in 1899 and he and Gore-Booth married in London on 29 September 1900. She was afterwards known as "Countess Markievicz". She gave birth to their daughter, Maeve, at Lissadell in November 1901. The child was raised by her Gore-Booth grandparents and eventually became estranged from her mother. She undertook the role of mother to Stanislas, Casimir's son from his first marriage, who then accompanied the couple to Ireland.
