I think it likely that your lady will be CATHERINE CARTY/Carthy on the 1881 census, she is living at 8, Plane Street Leeds, with her widowed mother, Bridget age 50, who came from Galway
Piece 4519 folio 41. She has several siblings still at home
I cannot find a Catherine Robinson, born Leeds , of the correct age. This Catherine, seems to have been 24 years old on the 1891 census, and came from Durham,she had two young children
Catherine Melia, died at 102 Freehold Street, on May 10th 1928, and was buried on the 14th at Killingbeck Catholic Cemetery . Grave section N , Grave No 99
Her son , William jnr died, age 20, and was buried at the same Cemetery 9th November 1918.
Section K Grave 73.
I am afraid that Catholic Marriages and Baptism are not online as yet
Hope this helps
