The name Octave, of Latin origin, is derived from the word 'octava,' which means eighth. It is traditionally given to the eighth child born into a family, following an ancient Roman custom. In musical terms, an octave refers to the interval between two notes with double the frequency, reflecting harmony and balance.
"Over a span of nearly ninety years (1880-1969), the name Octave saw varied popularity with no clear trend. The highest number of births was recorded in 1918 and 1919, with 18 babies each. However, from the 1930s onwards, there were consistently fewer than ten births per year, indicating a decline in its usage."
