Obviously, there was only one Hutsteiner family member ennobled: Heinrich Christian Huthsteiner.  Unfortunately I still did not find any document awarding him a title of nobility.

Within two documents of prussian military he was mentioned as “von” Huthsteiner, which is the usual prefix to a surname of a person who was ennobled or is member of a noble family.

Online and in some archives You may find records of aristocrats named as “von Huttstein”. But there is a type mismatch and transcription error included in these records. They always refer to the well known aristocrats “von Hattstein”, which are originally located in the south of Hesse/Taunus. Mismatching Hatstein/Hattstein and Hutstein can be found quite often.
