Written from Kinsale, County Cork · the 9th of May, 2026
Dear Mary,
I'm writing this from the harbour wall in Kinsale, County Cork, with a flat white going cold beside me and a view of the estuary that your O'Brien ancestors would have known well. The boats are coming in. A heron is standing on a bollard thirty feet away, absolutely motionless, watching the water with the patience of something ancient.
Cork people have a particular relationship with water. We're surrounded by it — the Lee running through the city, the harbour at Cobh, the wild Atlantic coast from Mizen Head to the Old Head of Kinsale. Your family name, O'Brien, comes from this part of the world — from Thomond, the ancient kingdom that stretched across what we now call Clare, Limerick and North Tipperary — but the O'Briens spread south into Cork over centuries, following the rivers and the coast, settling in the townlands and the harbour towns.
There's an O'Brien's Bridge on the Lee in Cork city. There's been one there since the fifteenth century.
I want to tell you about Cobh this month, because I was there last week and I couldn't stop thinking about the people who left from that harbour and never came back.
Cobh — it was called Queenstown when your ancestors would have known it — was the last sight of Ireland for over three million emigrants between 1845 and 1960. The Titanic's last port of call was Cobh. The Lusitania survivors were brought there. And in between those disasters, the ordinary boats — the cattle boats, the emigrant ships, the mail steamers — left from that harbour week after week, year after year, carrying people who had nothing left in Ireland and everything to hope for in America.
Standing on the pier at Cobh, you can still feel the weight of it.
What strikes me, every time I go, is how young they were. Most emigrants were between seventeen and thirty. They left with a single bag, a few pounds if they were lucky, an address in Boston or New York or Philadelphia written on a scrap of paper. They crossed the Atlantic in conditions we wouldn't put cattle in today. And they arrived with nothing but the name they carried from this island.
Your name, Mary. O'Brien.
Eight centuries old. Carried across an ocean by someone who had nothing else to bring.
I think about that a lot when I write these letters. The people who left Ireland carrying their names like seeds — and the gardens those names grew into in America.
The heron just caught a fish. Cork life goes on.
Go néirí an bóthar leat, a Mháire —
May the road rise up to meet you, Mary.
