I'm not able to read Japanese without aid and I'm not a professional researcher, but that seems to translate to "Sansaki" which comes up in a few search results, most notably the name of a shrine.
Please somebody correct me if I'm wrong, but;
散 "san"
咲 "saki"
and 子 means "zi" or "ci" meaning "child"
So... "little Sansaki" possibly?
Edit: I think you should contact the researcher you hired and ask them because it was missed
