I can't for the life of me find the labour activist Helena Molony in either the 1901 or the 1911 Census of Ireland. She's said to have lived with her brother Frank (a couple of years older than her) and his wife in Sherrard Street from around 1900 to 1910.
She was born in 1883 to Michael Molony, grocer, and Kate, née McGrath, in 8 Cole's Lane (off Henry Street just to the north of the Liffey); in 1885 her mother died, and in 1890 her father died. Her father had remarried, but she and her brother Frank did not get on with their stepmother and left home around 1899. Frank and his wife emigrated to the US in 1909.
I've found her birth in 1883 and her parents' marriage in 1876, and what's probably her father's death in 1890 (TB, NDU) and her mother's in 1885 (epilepsy, Cole's Lane); and possibly her father's remarriage in 1887 (to Catherine O'Hanlon; he's in Clanbrassil Street and a grocer, which sounds right, but he gives his father's name as Denis, whereas he named him as Michael in the earlier marriage…
