I mentioned some years back that the Dream Angus lyrics are attributed to George Churchill.

Here is different attribution:
"Like many Scottish children, I was brought up with this one. The words and melody imply that this is not a very ancient song; probably written about 1850 to 1890 or thereabouts. Certainly, my grandmother who was born in 1894 was sung Dream Angus by her mother, despite their first language being Gaelic. There are loads of little variations on the words, but the song remains essentially the same. My mother assumed it was her father in the title role, as his name was Angus. This is an ideal opportunity to personalise a song, inserting the name of your child into the chorus.

"A recent correspondent, Dr Donalda Smith, wrote "My mother (born 1905) always told me that the words were written by her cousin, Mary Fraser, who lived at that time in Edinburgh. It was performed by the Glasgow Orpheus Choir under Sir Hugh Roberton, and was a favourite with them." She goes on to mention that her mother was younger than Mary Smith and died shortly after World War I."
