In other words, it’s been a while – 101 years to be exact.
But on April 12 at 5:48 p.m., baby Aurelia entered the world at 8 pounds 3 ounces, with blonde hair and blue eyes.
“I’m a little at a loss as to what to do – I grew up with three brothers and haven’t spent much time around girls,” Scott, 27, a manager for a lumber company in Post Falls, tells PEOPLE. “But my daughter has been a lot of fun so far. Everyone is excited to have a little girl in the family.”
Adds Scott’s wife, Ashton, 26: “It’s been a huge mental adjustment.”
But a fun one.
“I was pretty certain until my four-month ultrasound around Christmas time that we’d be having another boy,” she tells PEOPLE. “When we learned we were having a girl, nobody could believe it. Everyone kept asking, ‘Are you sure? ‘”
Now that all doubt has been erased with Aurelia’s’ first cries, relatives on the paternal side of the Underdahls’ family are buying baby clothes in pink for the first time since 1915. The last girl in the family was Scott’s great-aunt Bernice, born in 1914.
With eight boys born over four generations of Underdahls, along with Scott and Ashton’s first child, Archer, now almost 2, “we never considered girl names until after we got the news at that ultrasound,” says Scott. “And even then, it took a long time to sink in.”
“I’d even bought ‘little boy’ ‘blue and brown owl bedding,” Ashton, now on maternity leave from her high-tech healthcare job, tells PEOPLE. “I finally exchanged it and decorated her room in Elizabethan purple, gray and yellow, instead.”
Close friends since the fifth grade, the Underdahls were high school sweethearts who married five years ago.
“Growing up, I was a tomboy,” says Ashton, who has one younger brother. “In fact, for my birthday in the second grade, I asked for a cement truck and I got one. So when I became engaged to Scott and found out there were no girls in the family, it wasn’t a big deal. We figured, ‘We’ll be having us some boys.'”
After watching Archer interact with his new baby sister, the Underdahls think they’d like to add at least one more child to their family at some point.
“Who knows? Maybe another girl?” says, Ashton. “It’s like Scott’s dad says: It took more than 100 years to create perfection.”
