Who are Trent Olsen’s parents?
Trent is the oldest of the Olsen siblings. He was born to parents Jarnette and David Olsen in May 1984, in Sherman Oaks, California. According to People, the 39-year-old goes by his middle name Trent, but his real name is actually James.
How many Olsen children are there?
There are six Olsen siblings in total. Trent, Mary-Kate and Ashley and Elizabeth were born to Jarnette and David Olsen, who divorced in 1996. David then married his second wife McKenzie Olsen in 1996, and had two more kids, Courtney and Jake. The youngest, Jake, who’s dabbled in modelling and acting, revealed to Runway magazine in 2016 what being raised in the family was like: “Growing up in our house was always interesting … there was a lot going on! I learned about respect from everyone in my family. In a family of six kids, you learn it’s not always about you.”
