Hannah Sheehy-Skeffington and Margaret Pearse c. 1921.

Margaret Pearse was the mother of Pádraig and William Pearse. A native of Co. Meath, she joined Sinn Féin after the 1916 Rising. She was elected a Sinn Féin TD for Co. Dublin in the General Election of 1921. She was scathing in her criticism of the Treaty: "I rise to support the motion of our President for the rejection of the Treaty. My reasons for doing so are various, but my first reason for doing so I would like to explain here today is my son's account. It has been said here on several occasions that Pádraig Pearse would have accepted this Treaty. I deny it. As his mother I deny it, and on his account I will not accept it." She left the Ard Fheis with de Valera in 1926 and became a founding member of the Fianna Fáil party. She died in 1932. Her daughter, also called Margaret, went on to serve as a Fianna Fáil TD and a senator.
