See my posting at #1096. I am the one who mistakenly thought it was a wedding picture and got all this started. Sorry!
Made the same mistake.
This website says the following about the picture of the Mom and Dad.
This undated photo released by Obama for America shows Democratic presidential candidate, Sen. Barack Obama’s father, also named Barack Obama, and mother, Stanley Ann Dunham (her father always wanted a son). Obama’s father left the family to study at Harvard when Barack was just two. This visit, when Obama was 10, was the last time he saw his father. By then Ann had remarried.
