scroll down to 'Reminiscences'. I find it odd that the letters from people who knew him during the period 60-61 do not refer to obama snr's 'marriage' ...
Thanks for the link! I notice the recollections include mention of the Atherton Centre and I wonder if that is where the YMCA was as well. In the newspaper article (when he graduated) he never mentioned a marriage or baby either. Kind of reminds me of the baby daddies of today.
Did you compare the people in the 1961 party photos with the Sr leis picture to see if any of them were in it?
