“This is such a positive moment in our lives,” Amy tells PEOPLE of the happy occasion. Despite her family being embroiled in a second scandal – following his molestation revelations in May, her cousin Josh admitted to infidelity and pornography addiction and is currently seeking treatment at a faith-based rehab center – Amy was f ted by most of the Duggar clan, who turned out for her big day.

The country-chic wedding took place on the grounds of Horton Farms near Bentonville, Arkansas. “We’re thinking there will be about 400 people,” Amy told PEOPLE ahead of the day – a small gathering by Duggar standards. Says Amy, “These are only our closest friends and family and their families.”

The hundreds of guests included Jim Bob and Michelle, her cousin Jessa and even Josh’s embattled wife Anna. “She’s been through so much,” says Amy, who enlisted Anna and Josh’s 5-year-old daughter Mackynzie as one of her flower girls, along with her young Duggar cousins Johanna, Jordyn, Jennifer and Josie. Her cousin Jill also made a stop at the wedding with her family, taking a break from the family’s mission work in El Salvador.

The color theme was rose gold and candlelight and the bride wore a sweetheart neckline gown designed by Essense of Australia.

Though she was happy to tie the knot surrounded by her loved ones, she’s also looking forward to moving on with her life. “I can’t wait to change my name”, she told PEOPLE earlier in the week. “It’s going to be a great day when Dillon signs that marriage license and my last name changes.”
