I don't recognise Taladh An Leinibh Losa offhand; the song most usually known as "The Christ Child Lullaby", Tàladh Chriosda, was written by Father (Ranald?) Rankin of Moidart in the mid 19th century.  An extensive text in Gaelic (29 verses) can be seen at George Seto's website:  www.geocities.com/Area51/Zone/6338/taladh.html

Some additional comment and variants in English can be seen in the Forum here, at:  Christ Child Lullaby, different verses?

There is also a translation into English made by Seamus Ennis from a migrant variant recorded in Ireland in the DT:  Christ Child Lullaby   -with midi.

Staff notation and mandolin tab based on the set recorded by Cathal McConnell can be seen at Nigel Gatherer's site:  Nigel Gatherer's Traditional Music Pages

Staff notation for another variant, with English text only, is at:  Famous Potatoes

These are examples only; a search through Google.com will return a good few more.
