Family Name and Clan

[Arlen]

McShane, mcdonald, macgregor, campbell etc. are not gaelic spellings of these names they are english spellings.

MACGHRIOGAIR - Gaelic.
MACGREGOR - English.

And yet, if you are speaking in English you anglocise things.
When I am speaking/writing in the Gaidhlig I use the Gaidhlig spellings and pronunciations of my name and anyone else I am referring to.
When I am speaking/writing in English I use the English spellings and pronunciations.

I also deeply appreciate that places like Canada and America have kept up Scottish traditions (Such as step dancing {not to be confused with Highland Dancing or Scottish country dancing}) which we lost over time and have recently been able to bring it back over to Scotland.

Here's the thing. To be part of a clan back in the day meant living on the land of and swearing fealty to a certain clan and chief. You didn't even need to share a name.
That is no longer, but there is nothing wrong with people celebrating and loving a shared heritage. Especially when they are carefully preserving things that we here in Scotland seem to carelessly lose and then regret so much afterwards.

So long as you are proud of who you are as an individual and are not simply living in the past I see no issue at all with showing pride for and interest in what made you.
