Robertia, derived from the Latin 'Robertus', which means 'bright fame', is an uncommon yet striking feminine variant of the traditional masculine name Robert. This name gained popularity during the medieval period but has since been infrequently used, making it a unique choice for parents seeking an exceptional moniker for their daughter.
"Interestingly, the name Robertia was given to five girls each in 1918 and 1919, followed by a spike of six in 1928 before dropping back down to five in 1929, totaling twenty-one births over these four years."
