Per Billy Wilson of the Motown Alumni Association. It was posted in a Barbara Martin thread in the main Motown forum but I thought I'd repost it for those who may skip the main thread.

Hello everyone. Barbara Diane Martin is dead. The exact date is not currently known, but I recently acquired ALL of her personal items from a storage sale! Officially she went under Diane Martin officially. She also worked with and for Motown up to the 80's when Motown was bought. As many of you know, she was the 4th original member of the SUPREMES. She left because she had gotten pregnant! The grueling traveling & touring would have been very tough for her at the time, even though her then husband was ok with her being with the group.
We [[The Motown Alumni Association) will be selling some of her BELONGINGS on: http://MotorcityBourique.com, and http://Offerup.com. We will also offer a letter of authenticity with each item sold, where it come from and how we acquired the possessions. For those of you that don't know who I am, I'm Billy Wilson, president of the Motown Alumni Association. We are the biggest advocacy group for the Motown stars in the world, and have been in business since 1995. You can contact me at:
