Calamity Origin and Meaning
Although this name literally means disaster, the use of Calamity as a descriptor of Martha Jane Cannery, aka Calamity Jane, was meant to signal that she was a good person to have in troubled times. Calamity Jane was well regarded as a frontierswoman and nurse, someone who was said to be extremely generous and compassionate to the sick and troubled.. Calamity's connection to the American West gives this a roguish name a sort of windswept charm about it. Indeed, the most controversial aspect of this name is its connection to the frontier wars that led to the dispossession of Native American peoples.
Controversy aside, you really don't want to name your daughter Calamity. There are plenty of other uncommon girl names starting with C that don't sound like jokes.
