First daughter Ivanka Trump's real name isn't actually Ivanka.

In fact, the first name of the daughter of President Donald Trump is Ivana, just like her mother.

Ivanka is a nickname for Ivana, similar to how a child named Robert could be called Bobby or Daniel could be called Danny. Or you could think of it like the TV show "Gilmore Girls," in which Lorelai Gilmore names her daughter Lorelai but calls her Rory.

Just as Donald Trump Jr. is named after his father, it makes sense that Ivana Trump would also want to pass her name onto the next generation.

In 2010, Ivanka Trump explained her name's backstory on Twitter:
