Thomas Rhett is now the proud father of two beautiful daughters, and in a new interview, he shares how he and his wife Lauren turned to their family trees for inspiration in naming the girls.

Rhett and Lauren welcomed adopted daughter Willa Gray in May after an arduous year-long process in adopting her from Uganda. By the time they brought her home they already knew they were also expecting a biological daughter, and they welcomed their newest family member, Ada James Akins, on Saturday, Aug. 12.

"Willa came from my mom’s dad, his name is Willard, which translated means innately brave. And so we felt like Willa was a beautiful girl name and also I think we thought it represented kind of her story, like you have to be strong to survive what she went through," Rhett tells his record label, Big Machine. "And then Gray is short for Lauren’s brother Grayson and we really love Grayson’s personality and we love him so much. We just thought Willa and Gray [fit] really nice together. We’re a huge double name family if you haven’t known."

They arrived at their other daughter's name somewhat differently. "Ada James, James comes from my uncle, my dad’s brother his name is James Elias," Rhett reveals. "So James is her middle name and Ada, Lauren said that she had a dream and she kept hearing the name Ada in the dream. And that is why we went with Ada. Pretty random but really cool."

Rhett is spending some time with his new family now before he releases his third studio album, Life Changes, on Sept. 8. The album’s first single, "Craving You," is a duet with Maren Morris that recently hit No. 1, and Rhett has just released the second single from the album, "Unforgettable." He’s been on the road on his headlining Home Team Tour this summer.
