The Clan Gunn

[neloon]

In all of his, we have to go back hundreds of years to a time of very low levels of literacy in 2 or 3 co-existing languages none of which had a standard orthography. So "Sven" was sometimes "Sveinn","Sweyne" etc. and could be readily confused with Scots Gaelic "soighainn" meaning "pleasant" (and which in Irish Gaelic is usually spelled "suibhne"). So "Son of Sven" might be "Svensen" (Swanson) or "MacSh?einn" (no "v" or "w" in Gaelic orthography) but which would have sounded (Macqueen) pretty much like "MacShoighainn" = son of the pleasant one.
On top of this, these names were not at that time surnames but patronymics. So, if someone called Calum had a father called Donald, then he was Calum MacDonald but that did not make him part of Clan Donald even though a (later) surname interpretation of any written document might make it seem so.
Maybe you Gunn-Macqueens should just go with whichever clan motto you prefer!
Gunn = "Peace or war!"
Macqueen = "Constant and faithful"
