Robertha is a unique and distinctive given name, combining the classic 'Robert' with the elegant 'a', creating a feminine twist on an otherwise masculine name. It's a rare find among names, making it stand out wherever it appears.
It seems like the name Robertha was quite popular around the early to mid-20th century, with a significant peak between 1915 and 1923, during which there were over 16 births per year on average. However, its popularity declined sharply after that period, with fewer than 15 births recorded in any given year from 1924 onwards. By the late 20th century, it had become quite rare, with only a handful of births recorded each year between 1965 and 1982. In total, there were 548 babies named Robertha born over this period.
