Ancestsors of Haagin Evenson

I was researching my great great grandfather, Haggin Evenson 1800-1865 about 4 years ago and a number of you were very helpful. Now I need to ask you to help me with three more names in Haagin line. I am not sure of the names and dates. Haagin Evenson was the father of Hans Hawkinson. This is what I have in my tree after Haagin Evenson. Son of Even Johnsen -1857 Even's father next in line Johannas Erikson (no dates) then johannas' father might be Erich Olson (no dates) and finally his father might be Ole Erichsen (no dates). I can't find any records I can trust without these dates. I know we have gone over some of this before but could sure user your help on this.
