Any info on Ole Syvertsen Lee

Hello. I posted here 6 months ago or so and now have a little bit more information and hope maybe someone can help. Ole Syvertsen Lee, born Sep 20 1850 in Norway. According to USA 1900 census, came to USA in 1859. According to marriage certificate (to Ingeborg Helene Thoen) his parents are Syvert Lee and Johanne Olsen. He had settled in St. Croix County, Baldwin, Wisconsin. I would like to find more info on the family. Such as what ship, where in Norway, any siblings, etc. Can anyone point me in the right direction?? I seem to come up with dead ends. Thanks for any assistance/suggestions you may have. sha.
