Hi Badger,
Welcome to BirdForum!
From The Historical Atlas of Breeding Birds in Britain and Ireland (Holloway 1996; Poyser):
Seems amazing that someone both witnessed and recorded their very first arrival, at a time when binoculars didn't exist, birding wasn't a widespread pasttime, and even the ability to read & write was probably not too common.
How many other British or Irish landbird firsts have actually been seen flying in off the sea? Precious few, I suspect.
