Unfortunately despite a long search, there doesn't seem to be any consistent history to the origin of the name Tachias available. Although there are birth, deaths and marriage certificates in that name. There just doesn't seem to be any information on the origin or meaning.
However I can say for sure that "Tachi" originates from Japan. Whether Tachias is a variant of Tachi, we are unsure.
May I suggest seeking a genealogist to help you trace it down using public records, which we don't have access to?
