Clifford Eggen - Clifford Eggen - full sibling, half sibling -- who is his father?

There are two profiles for Clifford Eggen - one that states his father to be Even Eggen; another that states his father to be Bardolph Ege. Both profiles have the same mother - Petra Strand Eggen Ege -- she was married to both men, but Clifford was born when she was married to Even Eggen. The profiles for Cllfford should be merged -- as they stand now, it appears that he is his own half brother. Then there a comment in the overview for Naomi Eggen that implies she is the daughter of Bardolph Ege. Can someone please sort this out.
