I don't want to seem discouraging, but only three of all these songs are not already in the DT and/or Forum. The new ones are

The Auld Scotch Sangs
The Auld Hoose
Granny's Hielan' Hame

You don't say whose website you got all this material from. Whoever they are, they don't seem terribly conscientious about crediting the writers of many of these songs. I was puzzled by one of their comments: [Mary of Argyll] "Written by two Englishmen, this song is as Scottish as any." I wonder why they didn't name the two Englishmen concerned? (For the record, they were Charles Jefferys and Sidney Nelson, who also wrote The Rose of Allandale) It has to be said, of course, that the set of Mary of Argyll in the Forum is not properly attributed either.
