Counting On Star Grandma Mary Duggar Was Found By Her Daughter After Drowning in Pool

Before Grandma Mary Duggar’s unexpected death, she spent some of the last hours of her life at one of the places she cherished most: church.

“On her last morning spent here on earth I drove Grandma to church where she worshiped her Savior. Later that afternoon, she went to meet Him face to face! I’d say that’s probably how she would’ve chosen to finish out the day if she got to pick,” Mary’s granddaughter Jana Duggar revealed in an Instagram post.

On Sunday, June 9, the Counting On star tragically died at age 78 of an accidental drowning in a swimming pool, Washington County Coroner Roger W. Morris confirmed to PEOPLE on Wednesday.

According to Morris, Mary was found by her daughter.

“Duggar slipped and fell into the pool and drowned,” Morris told PEOPLE on Thursday. “Her daughter Deanna discovered her body and alerted authorities, who pronounced her dead at the scene.”

News of Mary’s passing was first shared by the Duggars on their official Facebook page Sunday afternoon, where the “feisty” and “incredible” County On star was remembered by her famous family in a tribute post.

“We are so sad to share that Grandma Duggar (Mary) passed away Sunday afternoon, June 9th, 2019. Mary Lester Duggar grew up in Farmington, Arkansas and was married almost 50 years to J.L. (Jimmy Lee) Duggar who preceded her in death,” the post began. “Mary found great joy in sharing her love for Jesus and her own story of how at age 15 she asked Christ to forgive her for her sins. It was at that time she committed the rest of her life to live for Him, a commitment she kept with devotion.”

Grandma Duggar will be greatly missed!! – On her last morning spent here on earth I drove Grandma to church where she worshiped her Savior. Later that afternoon, she went to meet Him face to face! I’d say that’s probably how she would’ve chosen to finish out the day if she got to pick. – Grandma made a deep impact on each of our lives—first and foremost through her relationship with Jesus Christ, and secondly through her example of sharing the good news of salvation through Jesus with others! She would always be talking about the day she would see her Savior’s face and how much she looked forward to it! Yesterday was that day! She knew where she’d spend eternity and wanted everyone else to know that for themselves too. – This song reminds me of Grandma’s life. – “When We See Christ” Sometimes the day seems long, Our trials hard to bear. We’re tempted to complain, to murmur and despair. But Christ will soon appear to catch his bride away! All tears forever over in God's eternal day! — IT WILL BE WORTH IT ALL WHEN WE SEE JESUS! — Life's trials will seem so small when we see Christ. One glimpse of his dear face, all sorrow will erase. So, BRAVELY RUN THE RACE TILL WE SEE CHRIST. – May we all be reminded to run this race of life looking at the Author and Finisher of our faith. “Only one life, twill soon be past—only what’s done for Christ will last.” • #grandmaduggar #leavingalegacy #weloveyou

The tribute continued on to highlight Grandma Duggar’s life successes, such as her work as a prime real estate broker and her most important role of all — being “Grandma” to her 21 grandchildren and 13 great-grandchildren.

“Grandma Mary Duggar has been on the TLC shows, 19 Kids & Counting and Counting On with her family for over 15 years. She is greatly loved and will be missed so very much! She lived a tremendous life as a follower of Christ, a wife, a devoted mother, a loving mother-in-law, and a much-loved grandmother.”
