I'd second this. My brother took the test (saved me a job 😁) and while the results were pretty much as expected (68% Scottish Highlands, 27% Irish with a little bit of English and Scandinavian mixed in (our mum's grandpas were from Killarney in Ireland and Cornwall)), the links they gave to people you may be related to that have also done the test were surprising.
A couple of close relatives were mentioned to corroborate the findings, but also distant cousins I'd never heard of, with common names to the family that the people compiling the test would never have known.
