And who can blame them? If you don’t know, you don’t know (though hopefully you’ll remember after the first time you find said person). But it’s still interesting to see all the different names that pop up.

Take Ingrid Bergman. Her name has been variously typed online as Ingrid Bergmann, Ingred Bergman, Ingrid Bergmon, Ingred Bergmon (that one’s REALLY off), Ingrid Bergmen and more. They all sound roughly the same, so who’s to blame the perpetrators much?

Needless to say, that actress’ name is Ingrid Bergman. No double n, no o’s. Ingrid Bergman. Remember it and move on.

Here, then, is a listing of notable Bergmans outside of Ingrid’s family. It’s far from a complete list, but you’ll get an idea of how popular the name is.

- Alan Bergman, a lyricist and songwriter

- Andrew Bergman, a screenwriter and director

- Bo Bergman, a poet

- Carl Bergman, a biathlete

- Eva Bergman, a director

- Gustav Bergman, a mayor

- Ingmar Bergman, a stage and film director (who had contact with Ingrid during his time in the business)

- Jaime Bergman, a Playboy playmate and model in general

- Lawrence Bergman, a politician

- Marit Bergman, a musician

- Ulrika Bergman, a curler

Bergman is even the name of a lunar crater, named after chemist Torbern Olof Bergman from the 18th century. Pretty impressive, no?

And a couple she had indeed. Her first child, born in 1938, was Pia Lindstrom. Lindstrom was greatly affected by Bergman’s scandalous affair with Roberto Rossellini, as Bergman was forced to leave her child and flee the country, prompting Lindstrom’s father Aron Petter Lindstrom to fight for custody of her. Lindstorm today is an award-winning reporter with some acting credits under her belt.

But most of her children come from the same director who’d forced her to fled. Their first child together was Roberto Rossellini, born in 1950. But they didn’t stop there: two years after the pair got married, Bergman gave birth to twins.

The first was Ingrid Rossellini. Ingrid was apparently more of a scholar than actor, and she went to school to get her Ph.D in Italian Literature. She teaches the subject still. She also teaches courses in Italian Cinema, which somewhat runs along the family lines.

The other, more famous daughter is Isabella Rossellini, a model, actress, author and more. She’s been in the business for many years and doesn’t look to be slowing down: though her choices of roles seem to be getting ever stranger, as she most recently helped create and starred in Green Porno, a series of short films illustrating the mating habits of a variety of animals (dragonfly, bee, worm, snail, housefly, praying mantis and spider).

So that reputation can only be bolstered by tacking Ingrid Bergman’s name on as well. And just that thing was done a while ago when a rose was named the ‘Ingrid Bergman Hybrid Tea Rose’. A fragrant rose, the Ingrid Bergman Hybrid Tea Rose is selectively cultivated for its beautiful color (a dark red), and thus is popular (like most Hybrid Tea Roses) among professionals and mere admirers alike.

The Ingrid Bergman Hybrid Tea Rose was first cultivated in 1986 and named in honor of the actress, and continues to enjoy great success today.

Her role was a complex one in Anastasia. She played a confused, disoriented French girl who is paraded around as Grand Duchess Anastasia of Russia. She must convince a nation – including the Dowager Empress – that she is the real deal. Before being announced to be officially wed, however, she runs off with her true love, a general played by Yul Brynner.

Though an animated version was made in 1997 based on the original movie, it never managed to emulate Bergman’s fire as the would-be Duchess.

So when the two were cast together in a single film, the result was inevitably going to be a hit. The 1942 American romance Casablanca remains one of the world’s most well known love stories, and features both Humphrey Bogart Ingrid Bergman as the main characters in love.

Set in the Moroccan city Casablanca, the movie’s storyline centers around Bogart’s café, which sits in the battle liens between allied spies and Vichy and Nazi officials. Bogart and Bergman must wrestle with an earlier love they shared, despite Bergman’s being married.

Inevitably the pair must part, their relationship ending with the famous line “Maybe not today. Maybe not tomorrow. But soon, and for the rest of your life.”

Here’s the famous scene at the end of Casablanca with Humphrey Bogart & Ingrid Bergman:
