(I'm not related to Hans)
Hans Erland Brandt arrived New York 14 Mar 1898 on ship Norge from Copenhagen, and listed his last residence as Rønne. His destination was a "cousin Mrs Anna Fensen, Oslengo, Minn."
Rønne is a large city on the western coast of Bornholm, and has a Rosenvej street, possibly source of "rosenbry"
However, Hans was born 12 July 1870 in Neksø, on the eastern Bornholm coast, parents Christian Hansen Brandt and wife Ane Cathrine Lyster.
I've attached the birth record and here is his family in 1880:
