Mardis is of French origin, meaning 'of Mars'. It's a unique and unusual given name, often used for both males and females due to its unisex nature. In English-speaking countries, it's relatively rare, which adds to its distinctiveness. The name Mardis is not derived from any specific saint or historical figure, but rather is believed to have been created as a modern coinage.
"The name Mardis was quite popular in the early 20th century with a total of 16 babies named Mardis between 1922 and 1923 alone. However, there were no recorded births with this name for nearly four decades afterward until one birth occurred in 1967."
