While you can’t pick the gender of your baby (yet), many expecting parents have their fingers crossed for either a boy or a girl — but none more than one Idaho couple. And after quite a wait, the Underhaul family welcomed its first baby girl in 102 years. On April 12, Ashton Underhaul gave birth to Aurelia Marie Ann, with husband Scott Underhaul by her side. The couple found it hard to believe that they were about to disrupt a boy birth trend that dated all the way back to 1914.
Ashton told KHQ that her husband was incredulous when at 16 weeks they learned the gender. “‘He was like, 'Really? Really? Are you sure?’ He kept thinking, even though we were in the delivery room, he's like, 'What if they made a mistake and it's been a boy all along?’” That last girl born to the Underhaul family was Scott's great aunt Bernice. Scott told CDA Press that he was in disbelief at the news: "Everyone has been hoping for a girl… I didn't know what an Underhaul girl looked like."
The US has a tilted sex ratio — 51 percent of babies born are male and 49 percent female, making it slightly more statistically likely to have a boy. But nothing seemed to explain a four generation deficiency of females. Corry Gellatly, research scientist at Newcastle University, believes having consecutive boys, while unlikely, may make genetic sense. "Whether you're likely to have a boy or a girl is inherited. We now know that men are more likely to have sons if they have more brothers but are more likely to have daughters if they have more sisters," Gellatly said in a press release for his Family Tree study.
It seemed like the males in the Underhaul family were all out of X chromosomes. According to biology, the mother already has an X chromosome in the egg, and it is up to the sperm cell to change the gender (XY for boys, and XX for girls). And even though the chances of having a girl after giving birth to one or two boys does decreases slightly, it is a myth that if you have only boys, you “can’t make” a girl. And this family is proof! Aurelia is little sister to a 22-month-old brother, Archer.
The Underhauls will no longer rank among other record breaking girl-less family birth trends. Such as one famous Michigan couple, the Schwandts, who have had a total of 13 boys in a row — leaving statisticians scratching their heads.
The Underhaul couple is thrilled with their new addition, though still getting used to the change. "She's pretty quiet," Scott Underhaul told CDA Press. "So apparently girls are different than boys in our line." Conrad Underhaul, Scott Underhaul's father, couldn't be more proud, saying, "She's a cutie. We've been spoiling her a bit because it's just different finally holding a baby girl." He added, "Maybe it took more than 100 years to create perfection."
