If they were not legally married Stanley Ann would be a single mother. Only her name would be on the birth certificate.

"First of all, as shown by Crosby, all the announcements show the parents as married and living at the same address. “This is not merely a majority of the announcements, this is actually all of them. Every single one! Approximately 16,000 in all!” Crosby said. He continued, “This is a significant indication that the newspapers actually do not investigate the information provided by the DOH (Department of Health). If they did, they would have seen that there are more than 1040 births recorded in Hawaii in 1961 in which the parents were not married and/or only the mother is recorded as the parent, yet the papers still publish Mr. and Mrs. ‘Whoever’ in the announcement because that is the information registered, not medically verified.” If the DOH doesn’t include accurate information about the parents marital status for birth announcements, in all cases, what makes people conclude a native birth even though the DOH also omits accurate information about the location of the birth, as well? Crosby also discovered that the announcements are in a tale-tell order which exposes a shocking fact about Obama’s birth announcements. "Also," says Crosby, "just an interesting little side-note, we have all been told that Obama's parents were married sometime in early 1961. There are thousands of marriage application announcements published in these newspapers between 1960 and 1962, which were also published from registration information provided by the same DOH vital records office as Hawaii's birth registration announcements. There is no marriage application announcement for Dunham and Obama Sr. anywhere in the volumes I've researched."
I want to point out in my previous post I was actually asking or speculating not stating a fact.
“If they were not legally married Stanley Ann would be a single mother. Only her name would be on the birth certificate.”
The birth announcement would have read a “son” was born to “Mr. and Mrs. Dunham.”
