Her father was described as a "stockbroker" on Lynch's wedding certificate, but he is known to have pursued a number of careers, including journalism.
[1] As a result of her father's death she received her education at schools in Ireland, England, Scotland and Belgium.
Her article "Scenes from the rebellion", written for a suffragette paper, The Workers' Dreadnought gave an eye-witness account of the events of the 1916 Easter Rising in Dublin.
She was friends with Maud Gonne, Constance Markievicz, Hanna Sheehy-Skeffington, and with the Fabian writer, Edith Nesbit.
[7] Marcus Crouch in The Nesbit Tradition[10] describes Lynch's work as "the richest and most heart-warming of family stories."
Her works had many different illustrators, including the artists John Butler Yeats (The Turf-Cutter's Donkey) and Sean Keating (The Grey Goose of Kilnevin).
