Thelmah

The name Thelmah is a rare and somewhat obscure name, often considered a variant or elaboration of Thelma. The name Thelma itself was popularized by the novel 'Thelma' (1887) by Marie Corelli, which featured a Norwegian heroine. Corelli is believed to have either invented the name or derived it from the Greek word 'thelma' (θέλημα), meaning 'will' or 'wish'. Therefore, Thelmah carries the same etymological root and meaning.

While 'Thelma' gained some popularity in the late 19th and early 20th centuries, 'Thelmah' remains a much rarer spelling. Its usage is likely a stylistic variation or a unique choice by parents, emphasizing the Greek root more directly. The addition of the 'h' at the end might also be an attempt to give it a more distinctive or perhaps a slightly more 'exotic' feel.
