"When we first got in there it was kind of like a shock wave, like they didn't know that we were still actually still coming or if we were going to come at all,” said Williams.
The brothers arrived with diapers, pacifiers and baby bottles when they met the newborn, named Cason Knox Lashley.
"We explained everything and what we were here for and how we got to know that they were there,” said Williams. “They was pretty cool about it and they invited us in like we were just one of their family."
They brothers say they've received positive feedback from the community and the family.
"I mean basically, it doesn't matter how you look, as long as you come with a kind heart,” said Williams. “No matter where you come from, as long as you have a kind heart."
The brothers say the mix-up gained them a lot of new followers on social media. Baby Knox's parents posted a message on Facebook thanking the Williams brothers for their kindness.
