Emily Weddall and Constance Markieviez were born six months apart. Emily in September 1867 and Constance the following February. In early life their paths were unlikely to cross, as one was born into the aristocracy the other a clergyman’s daughter. One lead a comfortable existence in a grand house in Co. Sligo the other moved around frequently depending on the fortunes of her father. Constance Gore Booth was presented at court, Emily trained as a nurse.
Emily went on to enjoy an adventurous life when she qualified as a nurse, traveling to France, Germany and on to Russia. It was in the latter that she developed a strong social conscience, when she witness a group of prisoners, shackled together one night as they were being transported to Siberia, for minor crimes. Constance Gore Booth had that innately, taking side with the tenants on her father’s estate and organising sufferage meetings with her sister at Lissadell when she was quite young.

After coming out the Countess traveled to Paris to study art. Emily found herself in France too, possibly employed as a nurse, but it was a lucky trip for her as she first met the man who would become her husband. Incidentally, Constance Gore Booth met hers in France too. Emily married a retired sea captain Constance a count.
Their paths may have crossed earlier but in 1905 they were documented at the Seachtaine na Ghaelige parade in March 1905, part of the same Gaelic League branch, Craogh na Gluig Gluigi.
