In the Netherlands, the name became popular in the 21st century, primarily as a feminine name (at least when used as an official name on birth certificates). This was probably a by-effect of the new but strong popularity of Phileine, plus some (indirect) influence from long-popular French feminine names like Milou.
A known bearer of this name is the Dutch DJ Philou Louzolo (b. 1989). He was born in Zierikzee to a Congolese mother and a father who is half Nigerian and half Sierra Leonean.
Philadore is also the name of the protagonist in Eliza Haywood's 1727 novel 'Philadore and Placentia'.
Though it has never been popular in the English-speaking world among Christians, it has historically been a common name for Jews, who have used it as an Americanized form of names such as Isaac, Israel and Isaiah.
This name can also be given in reference to the city in Italy, as in the case of Florence Nightingale (1820-1910), who was born there to British parents. She was a nurse in military hospitals during the Crimean War and is usually considered the founder of modern nursing.
