Seeing as this name is derived from Greek δυσμη (dysme) meaning "sunset", its original spelling in Greek should be Δυσμας (Dysmas), with Dismas being a variant (if not anglicized) spelling.With that said, the use of Dismas as a given name has not solely been restricted to Judeo-Christian Legend, in that it has been used in real life for real people as well. For example, there was the Bohemian composer and violinist Dismas Hataš (1724-1777) and the Czech baroque composer Jan Dismas Zelenka (1679-1745). In the Netherlands, in the year 2014 there was a total of 10 bearers (of all ages) in the entire country. The name has also been used in other countries, such as Austria, Germany and even the United States of America. Yes, the name can certainly be considered old-fashioned (and therefore rare) nowadays, but there is no question that it has been used frequently in several countries in older times.- https://it.wikipedia.org/wiki/Disma_(nome) (in Italian; mentions the Greek spelling among others) - Dismas Hataš: https://en.wikipedia.org/wiki/Dismas_Hata%C5%A1 (in English) - Jan Dismas Zelenka: https://en.wikipedia.org/wiki/Jan_Dismas_Zelenka (in English) - http://www.meertens.knaw.nl/nvb/naam/is/Dismas (in Dutch) - https://familysearch.org/search/record/results?count=20&query=%2Bgivenname%3ADismas.
