If Sören (
Soren) was a common name in USA, then I could understand if there was a special American pronounciation. But I don't think it is that common. So I ask myself, why choose a forein name which you don't know how to pronounce? In this case, not how to spell either, since Sören is not spelt with an O, but with a Swedish Ö or a Danish Ö, which is like an O penetrated by a dash, /.
It is not totally subjective, the name has an origin and an original pronounciation.
"You sought a flower and found a fruit. You sought a spring and found a sea. You sought a woman and found a soul. You are disappointed."
"It does not become me to make myself smaller than I am." (
Edith Södergran 1891-1923)
