Current of reindeers

My surname is Renström, means current or stream of reindeers or something like that. I have lived in a couple of countries by now, and they don't get it right anywhere. The most common issue is they tend to want to swap the n and m, making it "Remstron", and at Yahoo! I am "Renstrm" as the mail we use cannot handle the ö.

Maybe here in San Francisco they will be able to say it correctly, because we are not alone! This truck was parked just outside our kitchen window, and as you can see it is the good folks from "Renstrom Plumbing" coming to fix your sink!
