Whilst in Paris, he met Constance Gore-Booth (later known as the Countess Markievicz). They married in London in 1900 and their daughter, Maeve, was born the following year. From 1902 the couple lived in Dublin.The largest part of his art collection is held in Dublin, some remain in Poland (National Museum, Kraków and in private collections). His talent points itself particularly to the large oil portraits of Polish presidents Piłsudski and Wojciechowski.Markievicz was part of the literary circle that centred on W. B.

He also wrote the screenplay of a 1920 Polish film, Powrót, directed by Aleksander Hertz.Towards the end of his life Markievicz was active in Warsaw, as well as a correspondent for English magazines, such as the Londoner Daily News. A catalog for his works is still pending.He died in Warsaw, Poland, in 1932.
