I looked at the tree, as you asked. Has date of immigration for Marie as 1908 and ties that fact to an Ancestry.com immigration record. But that Marie is born in Skien and has a father Anders.
Back in an edit to clarify: therefore the cited immigration is the WRONG Marie.
On the tree Marie children listed as William Irving b 1916-1953 and Bennie Roy 1919-1998. The line that is followed forward in time is Bennie and wife Gayle Alexander. Must be a close relative to you who created the tree.
Your local library probably subscribes to Ancestry and if you can grab an hour there, sometime, that's another way to access Ancestry without subscribing.
Correction: Ole Christian Larsen parents given (on the Ancestry tree) as Lars P LARSEN and Louise OLSEN, no dates, no locations. Just to clarify - his correct parents are Lars Petter Olsen and Olea Marie Eriksdatter (or Eriksen).
