Yes, Gutzon Borglum, the renowned sculptor of Mount Rushmore, had children. His daughter, Mary Ellis Borglum Varnes, was born on December 27, 1916, and was an artist herself, contributing to the Mount Rushmore project. His son, Lincoln Borglum, born on December 12, 1912, also became a sculptor and continued his father's work on Mount Rushmore after his passing. Both children were actively involved in the family's artistic legacy.
