Supermodel Karlie Kloss and her spouse, entrepreneur Joshua Kushner, have expanded their family, welcoming their third child, a daughter named Rae Florence. Born on September 18, 2025, her arrival adds to the couple's two sons, Levi, aged 4, and Elijah, aged 2, making them a family of five. This joyous announcement was made via a black-and-white Instagram post, adding a celebratory note to the approaching Jewish holidays. The article provides an in-depth look at the etymology and popularity of the names Rae and Florence, offering insights into their significance and historical usage.

Karlie Kloss, celebrated for her successful modeling career and her role as the founder of Kode with Klossy, a program dedicated to empowering young women in technology, exchanged vows with Joshua Kushner in an intimate Jewish ceremony in October 2018. The couple has since built a growing family, and the latest addition, Rae Florence, was introduced to the world through a heartfelt social media update. The post not only revealed the baby's birth date but also her unique name, which carries both English and Latin roots, signifying 'ewe' and 'prosperous, flowering,' respectively.

The name Rae, while English in origin, also serves as a diminutive of the Hebrew name Rachel, aligning with the couple's Jewish heritage. Its historical popularity saw it feature in the top 1,000 baby girl names for most years between 1900 and 1982, though it has not appeared on the boys' list. Noteworthy individuals sharing this name include actress Rae Dawn Chong and WNBA player Rae Burrell, with singer Carly Rae Jepsen also bearing it as a middle name.

Florence, a name derived from Latin, translates to 'prosperous' or 'flowering.' This name enjoyed significant popularity in the early 20th century, consistently ranking in the top 20 until 1924. After a period of decline, it reappeared on the popularity charts in 2017, currently standing as the 435th most popular name for girls. Interestingly, Florence also made appearances on the top baby boy names list between 1900 and 1914. Famous personalities named Florence include actress Florence Pugh and singer Florence Welch of Florence and the Machine.

The couple's choice of names for their children, Levi, Elijah, and now Rae Florence, reflects a blend of traditional and meaningful selections. These names, rich in history and significance, mark the continued growth and happiness of the Kloss-Kushner family, as they celebrate this new chapter with their third child.
