Sofia Gustavsdotter( vasa) and her husband Duke Magnus II av Saxon-lauenburg

[Maxine Morrison]

I have been trying to find out more about Sofia Gustavsdotter Vasa and her husband Duke Magnus II av Saxon- Lauenburg.
I have been trying to find pictures of them and would like to know more about Duke Magnus II as to his life as a child before he married Sofia.  
Was there married prearranged ?
I know he was mean to her, but what was his childhood like and is there any pictures of him?
You see; they were my grandparents many times removed.
I have the proof.
Thank you,
Maxine
