Hi, yes Julia died 3rd sept 1937 and Laurence died 4th sept 1956. They're buried together near the tower in glendalough. Dad is in the process of putting a new headstone up with both their names on it, and baby tom who died in the 1940s. We were down there last week, my kids love grandad telling his 'olden days' stories!!!!I don't know if Sarah outlived all her siblings.... Over the next couple of weeks I'll try to get dad to put down on paper all the names, etc..... His sister Nuala will be over during the summer too so I'll pick her brains too. Will email you when I get to do this.
