I suspect your Richard And Anastasia Shortis are part of my family. It begins with Richard Shortis who married Anastasia O'Neill circa 1760 and lived Carrick on Suir and at Portlaw. Richard was a proctor. He and Anastasia were murdered in 1799 and were buried at Portlaw (grave is online). There are online accounts of the murder as it was quite horrible and politically motivated.
They had 2 children that I know of - Edmund and Sarah. I suspect also a James. Edmund stayed in Carrick. Sarah married a soldier in the Dorset militia about 1800 named Demas Vincent. Sarah & Demas eventually settled back in his home town Dewlish Dorset. Their two daughters, Amelia and Elizabeth both emigrated to Australia. Elizabeth is my ancestor. I suspect all 'Shortis' in Carrick are descendants of Richard & Anastasia.
