Mar Sutra Sutra - Could Be My 50th Great Grandmother- What Evidence or Documentation is Available?

Hello,

This individual, could be my 50th great grandmother, however, what is the real name here? "Mar Sutra Sutra seems unlikely. Also, what evidence or documentation do we have at hand that indicates that she ever existed? Such as documenting how she is connected to Rav Papa? That she and Rav Papa procreated children?

Thoughts? Documentation/evidence please?
