Two newlywed couples and the parents of two young children were among the victims of the deadly upstate stretch-limo crash that killed 20 people, according to reports Sunday.

The stretch was rented by Axel and Amy Steenberg, who were just hitched in June, and headed to a surprise birthday party, reports said.

“They rented the limo with some families, and I don’t know exactly what they were doing,” Axel’s stepdad, Lester Andrews, told the New York Times. “There’s just a lot of confusion, so many people died. Their mother is looking for some answers. She wants to know what happened to her sons.”

The ride careened through the intersection of Route 30 and Route 30A in Schoharie, about 35 miles west of Albany, shortly before 2 p.m. and smashed into a packed parking lot, killing all 18 people inside the speeding vehicle and two bystanders outside a cafe that’s popular with fall leaf-peepers.

“I just wanted to say Axel Steenburg I love you more than words can say!” reads his newlywed wife’s final Facebook post Oct. 3, just three days before the crash. “You are such an amazing man and entertain all my crazy ideas. Even when I move a couch just to move it back to the original place. Thank you for being so kind and loving xo”

Steenburg’s older brother Rich, 34, was also among those killed, the Times reported.

“It is beyond devastating for everyone who knew them all,” Andrea Hojohn Orokos wrote of the brothers on a GoFundMe page for the siblings.

Newlyweds Shane and Erin McGowan were killed as well, according to family.

Erin’s aunt, Valerie Abeling, said the group was headed to a birthday party.

“She was a beautiful, sweet soul — he was, too,” the aunt said of the pair, adding that her own daughter had been invited to the party but couldn’t go.

Erin and her husband had a “beautiful wedding in June,” Abeling said — “They had everything going for them.”

Shane’s mother, Susan Minicki McGowan, said in a heartfelt post Sunday, “Our family will never be the same after the tragic deaths of Our Son Shane and Daughter Erin…”

Another relative, Anthony Vertucci, added in a separate post, “I don’t even know what to say… just darkness and devastation for my family, Shane’s family and all of the families involved.”

Adam and Abby Jackson also died, according to a GoFundMe page set up for their young daughters, Archer, 4, and Elle, 16 months.

“Adam and Abby were amazing parents to these girls and taken much too soon,” reads a post there by organizer Sarah Maltzman, who identifies herself as a friend of Adam’s mother.
