Kaitlin Olson is a popular American actress and comedian, best known for her roles in It’s Always Sunny in Philadelphia, The Mick, and Finding Dory. But is she related to the famous Olsen twins, Mary-Kate and Ashley, who rose to fame as child stars in Full House and later became fashion icons? The answer is no. Despite the similarity in their last names, Kaitlin Olson and the Olsen twins have no family connection whatsoever. Here are some facts that prove it.
Different Spelling of Their Last Names
The most obvious clue that Kaitlin Olson and the Olsen twins are not related is the different spelling of their last names. Kaitlin’s surname ends with “son”, while Mary-Kate and Ashley’s surname ends with “sen”. This indicates that they have different origins and ancestry. According to Ancestry.com, the surname Olson is derived from a Scandinavian patronymic meaning “son of Ole”, while the surname Olsen is derived from a Danish or Norwegian patronymic meaning “son of Ola” or “son of Olaf”.
Different Parents and Siblings
Another way to confirm that Kaitlin Olson and the Olsen twins are not related is to look at their parents and siblings. Kaitlin is the only child of Donald Lee Olson, a publisher, and Melinda Leora, a nurse and the founder of Earth Mama Organics. She was born in Portland, Oregon, and grew up on a farm in various parts of Washington state.
Mary-Kate and Ashley, on the other hand, have four other siblings: an older brother Trent, a younger sister Elizabeth (who is also an actress known for her role as Scarlet Witch in the Marvel Cinematic Universe), and two half-siblings Courtney and Jake from their father’s second marriage. They were born in Sherman Oaks, California, to David Olsen, a mortgage banker and real estate developer, and Jarnette Jones, a personal manager.

Kaitlin Olson and the Olsen twins also have different careers and achievements in the entertainment industry.
