How can he be a fostri of Nevstein and Ingrid?
They died in the 1050's and he were born 1094, also his last name is Magnusson which indicate that his fathers name must have been Magnus.
Toresfostre indicates that his mother is Tore Ingridsdotter.

Nope, Toresfostre tells that he was a foster child of a man named Tore.
Anyhow, you are right about the parents (Magnussson means "the son of Magnus) and this bad connection is just one of many we have found in this area.
