A 99-year-old woman has welcomed her 100th great-grandchild just a few months before her 100th birthday.
Pennsylvania resident Marguerite 'Peg' Koller met great-grandchild number 100 - Koller William Balster - earlier this month.
The latest addition to the clan was born on August 4, according to a report by Good Morning America.
Matriarch Peg was said to be "absolutely ecstatic" about young Koller's birth - though she's certainly no stranger to welcoming great grandkids into the family.
Peg and her late husband William shared 11 children in total. They, in turn, went on to have 56 grandchildren, who in turn provided Peg with a whopping 100 great-grandchildren.
However, for a while, it was uncertain whether Koller would make the 100th spot. His mother Christine Stokes Balster explained that she and her cousin Colleen were due to give birth around the same time and that neither could say for certain whether their baby would be Peg's 100th great-grandchild.
"It was a race to 100. My cousin Colleen and I were just a day apart [for] our due dates, and she had the 99th great-grandchild, who is absolutely healthy and beautiful," Christine said.
She added that they are "just grateful, blessed to have another few babies joining this great family."
With 100 grandchildren to her name, Peg can now begin looking forwards to her next big milestone - turning 100 in November.
While it may seem impossible to imagine now, the matriarch's enormous family almost didn't exist. As a young woman, Peg had her heart set on a childless life in a convent, where she was planning to become a nun.
Metro reports that Peg only decided not to take the veil when she fell in love with her future husband William, and he convinced her to get married and start a family instead.
In the end, Peg and William had so many children that it's almost impossible to get everyone in the same place at the same time.
Christine explained that the family have to do big events in "heats", so that everyone can get some time with each other.
