Help needed on Herm Hamnqvist photo

[Janet Williams]

I have a photo of who I believe was the captain of an immigration  ship on which my great grandmother was born on (6-8-1866).  It is dated 1898 and signed Till Dana Linnea Lindholm from her godfather Gustaf __ing.  I can't read his complete last name.  The photo was taken at the Herm Hamqvist studio in Stockholm.  I don't know what year the photo was actually taken though. Can anyone help me?

Herman Hamnqvist (1865-1946) had a studio in Stockholm 1890-1917.

Janet, can you scan the dedication and put it up here?

Dear Janet!
 
What was the destination of the ship? If America, you can found information about the ships on www.ellisisland.org/. Unfortunately, I seem to have a routing problem with my broadband connection so I can't log on the the web page and look it up for you.
