Tied in with notions of national and spiritual independence for Scotland the Solan Goose is also symbolic of nurturing family relationships – as it is said to mate for life.
The notion of the Celtic Spiritual matriarchy that is symbolised by the Scottish Wild Geese however is also intimately tied up with prophesy made by a Scottish Seer c.a. 1450AD.

This scottish revelation speaks of the coming steward of advent ..

‘ syne all the lentryne but leis and the lang reid, and als in the advent, the soland stewart was sent ..’ [c.a 1450]

then all lent, without lying, and the long reid, and also in the advent, the solan goose was sent as steward.

This prophesy sounds as if the Stewards are actually the Stewarts and can be read to mean that the Stewarts/Stuarts were going to be sent by God to be custodians of Scotland at some point.
