Genealogical conundrum

[davidlpope]

Would it be insincere to claim these clan connections? Or should the only claimed connections be those that are blood?

I don't think that most clan associations really care at all how tenuous one's connection to a "clan" is. That being said, what is the benefit to claiming these "clan connections"? More "justification" for wearing a particular tartan?
I'm not trying to be argumentative here, just trying to understand what purpose "making this connection" would really serve.

Cordially,

David
