This is my first post here, although I've lurked for a bit, so hopefully I'm doing things right
I recently discovered from family that my ancestor Mary Duffy (aged 44) was killed in the Bachelors Walk shooting of 26 July 1914 - the day of the Howth gun running. According to lore, she was the sister of my great-great-grandmother Elizabeth Tighe (nee O'Brien). I've also been told she is buried in the Republican plot in Glasnevin - I have the burial records to hand, but I have no idea if the details cited would refer to that plot or not.
She can be found on the 1911 Census at 20 Lower Liffey Street, which sounds right - I got the address from a previous thread
here on the Bachelors Walk shootings - with her husband, son, and nephew Thomas Tighe (whose existence I hadn't known about, so I presume he is not Elizabeth Tighe's son - unless it happens to be a middle name or some such thing?)
I suppose I'm looking for any further details linking her with the O'Brien family. Elizabeth Tighe is buried with several O'Brien relatives, as well as the purchasers of the grave who have the name Willis (they seem to be related through their daughter who married an O'Brien). I can't find any links with Mary at all, other than this mysterious Thomas Tighe.
Mary's husband Owen Duffy died in 1926, according to Glasnevin's records, and was buried in another plot, but no names show up that look familiar there either.
Any idea of where to begin the search? I've already looked up the FamilySearch website but the dates here seem just a little too late to be useful. I thought that given the notoriety of her death, there might be a little more research out there to help me out. The Irish Genealogy website might have something, but it seems a little hit and miss, and I've no idea how to verify any details found through it - O'Brien is a common name, after all.
Thanks in advance for any details you might find out.
