Please help me find this!!!

Shawn Robinson is an incredible singer from the 60s and I’ve been obsessed with her for a long time . She has 400 monthly listeners on Spotify but on different accounts probably just archives. She is overall quite unheard of, and has been in many pieces with piero piccioni as vocals. Her most recognisable song would be “my dear heart” little to no any info on the web other than a record archive website. I spoke directly with piero piccionis offical account and they had explained to me that even in their archives they didn’t have much on her only one source from that archive website. I’m reaching a dead end here does anyone have any info on her?
