Marla Aster (Koinonian)
This  manifestation of Marla Aster was created following the accidental death of the Human Marla Aster on the Koinonian homeworld in 2366, as a means to comfort her now orphan son Jeremy Aster. 

Unknown to the Enterprise crew, the planet was inhabited by non-corporeal Koinonians. They felt Jeremy's pain and created a manifestation of Marla Aster with the intention of raising him on their planet in a recreation of his old house on Earth. The Enterprise crew intervened and made it clear that Jeremy would not get over the death of his mother. Jeremy asked the replica to leave. ()
