Netty is believed to have originated from the Dutch name Annetje, which was originally a pet form of Anne. It has gained popularity as an independent given name over time. The name Netty is often associated with simplicity and familiarity, perhaps due to its shortened form being widely used in everyday speech.
The name Netty was quite popular at the start of the 20th century, with a peak of 11 births in 1920. However, its popularity seemed to wane over time, as there were fewer than 10 births per year after 1935. Overall, the name appeared 144 times in birth records between 1913 and 1954.
