Ginnifer Goodwin and Josh Dallas have named their baby boy Oliver Finlay Dallas.

The 'Once Upon A Time' co-stars, who got married in April, welcomed their first child into the world on May 29 and have given the tiny tot the popular modern moniker, according to a birth certificate obtained by TMZ.com.

According to the legal document, the couple's new bundle of joy was also delivered by Dr. Paul Crane, the same medical professional who helped Kim and Kourtney Kardashian throughout their pregnancies, at the Cedars-Sinai Medical Center in Los Angeles.

The loved-up pair are yet to confirm their baby's name, but Ginnifer previously admitted she was having difficulty coming up with suitable monikers.

She said previously: ''Naming a child with the last name of Dallas is a little more complicated.

''[We won't have] a first name that begins with a D because it gets porn-y. And nothing geographical because it sounds like an airport.

''[Josh] was like, 'Boy or girl, Austin Dallas.' I was like, 'That is an actual place where planes land. We can't do that.' ''

Meanwhile, news that Ginnifer, 35, was expecting a baby began to swirl in November last year shortly after the pair announced their engagement.

Josh, 32, said at the time: ''We are so thrilled... and can't wait to celebrate with our friends and family including our second family at 'Once Upon a Time'.''
