Jim Bob and Michelle Duggar

Jim Bob and Michelle Duggar have named their unborn daughter and scheduled a memorial service following Michelle's miscarriage last week, Us Weekly reports.

Jubilee Shalom Duggar, who was due in April and would have been the couple's 20th child, will be remembered at a ceremony Wednesday. A private memorial was held Sunday at the 19 Kids and Counting stars' home.

Michelle Duggar suffers miscarriage

Michelle, 45, was at a routine check-up on Thursday to find out the sex of the baby when her doctor was unable to find a heartbeat.

"On behalf of the whole Duggar Family we would like to thank everyone for their prayers, e-mails and outpouring of love," the couple wrote on their website. "As our whole family is grieving, we also know that God promises to work all things for good in our lives. We rest in knowing, that even though our child has departed this life that we will one day see each other again in heaven."

Duggars expecting 20th child

This was the Duggars' second miscarriage. Michelle miscarried during her second pregnancy. She was taking oral birth control at the time, and says this is one of the reasons she and her husband have since left the number of children they have "up to God."

The Duggars' youngest child, Josie, also experienced medical problems when she was born three months' premature in December 2009.
