If you're currently thinking about potential baby names, what do the names on your shortlist all have in common? Some parents will opt for names that all fit a certain theme, while others will be naturally drawn to monikers with a similar sound.
And according to a baby name expert, more often than not parents are drawn to a particular vowel over all the others in the English language - and it's the reason why names like Olivia, Oliver, and Noah continually top baby name lists.
SJ Strum claimed that a phenomenon known as the "O Factor" is responsible for certain names remaining timeless, as it's believed the letter O is the "most distinct vowel" in the English language, making it a perfect pick for a baby name.
