The early OS forms relate to Gaelic names in the area now occupied by Happy Valley.
Dail Dhomhail. This is the Gaelic name of the area slightly North-West of the area now
called Happy Valley. (East of where Dail Dhomhail once was is now Gleann Domhanaidh.)
Tom an t-Sìthein. This is a small hill within the current site of Happy Valley, now the
site of Laundry Cottage.
This is a modern English / SSE name relating to a site that previously had no specific name in Gaelic. No translation would have any historic or local validity.
