Seamus Heaney sure is the authority on family: he was the first of nine children!
The author and his wife, Marie Heaney, have a lot in common. His leading lady also came from a large family (seven kids), and is also a writer (she published a book about Irish myth).
A poet and a playwright to boot! Heaney also wrote a play called The Cure at Troy: A Version of Sophocles' Philoctetes, which was published in 1991. (Source.)
