Sonequa Martin-Green is a mother of two!

The Walking Dead and Star Trek: Discovery actress, 35, and her husband, fellow Walking Dead star Kenric Green, are the proud new parents of a daughter named Saraiyah Chaunté Green, born on Saturday, July 19, Martin-Green shared in an Instagram post Tuesday.

"We welcomed our sweet baby girl last Sunday, July 19th at 8:32 in the morning," she wrote. "It was a profoundly beautiful home birth, and now both of our children have been born in the water. We never felt that anything was missing, but now that she’s here, we feel a perfect sense of completeness."

The caption continued, "Her name is Saraiyah Chaunté Green, she’s got Mommy's initials and Mommy's middle name. She's utterly perfect, just like her brother. Thanks be to Yeshua, she's the final piece to our Love-given puzzle."

Alongside the caption, Martin-Green shared several photos of her with Saraiyah, as well as shots of dad Green and big brother Kenric Justin II, whom Green, 38, and Martin-Green welcomed in January 2015.

Martin-Green made waves as Sasha in earlier seasons of The Walking Dead, before her character died in the season 7 finale of a self-inflicted poison capsule, taken in an effort to help her friends against Jeffrey Dean Morgan's Negan. She currently stars on Star Trek: Discovery in the lead role of Michael Burnham.

Green stars in a recurring role as Scott on The Walking Dead, and has been in series like The Originals and Hawaii Five-0. He also appeared as Mike Burnham in a season 2 episode of Star Trek: Discovery titled "Perpetual Infinity."

The two tied the knot in 2010, and confirmed the birth of their son exclusively to PEOPLE in January 2015.

"We thank God for this incredible blessing," the then-new parents told PEOPLE of Kenric II. "We are overjoyed. He's the coolest little man ever."
