Thank you all very much. I'm still hoping the Chow lady will come through for me and let me use "of".
If not, I think we'll have to go with
Dubhgall fae Oban. I have rather belatedly counted the spaces I have and only 3 are free. Twit that I am. Fae is slang but it fits and is not incorrect. I don't know what that says about me, that I prefer improper over incorrect.
According to other sources I consulted:
bho = from, but in the sense of time or distance.
Dubhgall an t-Oban is too long and apparently makes no sense.
Dubhgall ain Obain is apparently THE correct way to say it but is too long and to leave out that extra "i" in Oban would make it incorrect.
Dubhgall as an Oban I'm told might be acceptable but is too long. There should be an accent grave on the a in as.
