Thanks, gran, for all of your diligent searching.Looks like we have had a similar experience.I also used the clues you referred to: DM,image title etc. So far no break in the case..

Splodge,It could the older Ella Fitzgerald,but I still can't be certain. I smudge painted the image in B&W and want to put it in my web gallery,so I am trying to contact the photographer to request permission to post the painting.But if it can't be found,I have learned a good lesson. On potentially sensitive images, I need to check the sources, when I first download the image.

Kittie,as I said,I'm not placing any bets in Vegas that its your mom..Who is,at best, a most and very incredible longshot ..

Well, if it does say DM_headshot, then chances are it is the woman I found, Donna Marie Christian, and she may very well have been on CNN several times, not as a singer, but as a politician.
