Yeah I jut looked up some examples from this list <https://www.bbc.co.uk/news/uk-england-somerset-49813249> starting with 'Frome'.
The first video hit had someone pronouncing it rhyming with 'home' when it's meant to be "Froom".
Ok, so it got 'Ballachulish' from a video specifically about Scottish Gaelic. (As an aside - how is 'Omagh' difficult?)
