There is a slight correction that needs to be made in your chronology.
She was married to Soetoro first, then Obama, then remarried Soetoro, according to these sources. Source 1, Source 2
Ridiculous. Stanley Anne Dunham married Sotero after Obama if she got married at all to Obama Sr.
In Source 2, the blogger uses the word "remarried" again with no source posted (it's likely just info gathered from news stories), or any indication that Dunham had married Soetoro before Obama. Again, it's not a credible source, and I suspect it's a grammatical error (since there are others on the page). It probably should read "She remarried. Her second husband's name was Lolo Soetoro..."
You could call both of these well-intentioned "genealogical junk," but not sources.
