I have recently posted my family tree on Ancestry.com. Captain Christian Jonsen Skinstad is also one of my ancestors. If you ck out the Oihus Family Tree you will obtain all of the ancestors for the captain that I have found so far. This info was obtained from a bygdebok from Nes parish in Hadeland, Norway. I have documented all of it thru microfilmed parish records so it is as accurate as I have been able to make it. I would be happy to collaborate further with you if you wish.
