When Bronte Kollis was born on December 16, 2019, she joined a very special birthday club – she is the fourth generation of her family to share the same birth date.
Bronte's amazing family legacy began when her maternal great-great-grandmother Doreen May Nissan was born on December 16, 1914.
On December 16, 1936, Doreen gave birth to a son, Joel George Bullock, making it two generations to share the same birthday.
The December 16 birthday skipped the next generation, but fast forward to 1987, and Joel's daughter Wendy gave birth to Natalie on December 16, making it three generations to share the same birthday.
Now 32 years later, Natalie has ensured the statistical coincidence carries on to another generation, after giving birth to daughter Bronte on December 16, 2019.
Natalie says she and her husband Alexander Kollis didn't realise the significance of Bronte's birthday until this week, when her aunt did some digging in the family tree.
"I didn't even know about it until this week when my aunt Sally, my mum's sister, did some investigating and sent it to my mum, who sent it to Alexander," Natalie says.
Natalie is also mum to three older children, Cayden, 12, Tayah, nine, and Knox, almost one, none of whom were born in December.
Baby Bronte was born six weeks early after a terrifying medical emergency.
"My water's ruptured at 33 weeks and I was diagnosed with a placental abruption, which is when the placenta comes away from the uterus wall," explains Natalie, who was rushed into an emergency caesarean before Bronte was safely delivered.
After several days in neonatal intensive care and 10 days in special care, she will finally go home on December 31, and one of their first visitors was Bronte's proud great-grandfather Joel. Great-great-grandmother Doreen passed away in 2003.
Natalie says she is excited about the lifetime of shared birthday parties to come.
"My mum throws a birthday celebration for me and my pop every year so now it will be even bigger. I can't wait for next year," says Natalie.
According to Guiness World Records, the record for most generations born on the same day is four, and is shared by six families, of which four are from the US, one is from Japan and one is from Finland.
It is not known if this birth will count as record-breaking because one generation was skipped.
Essential Baby attempted to contact University of Sydney mathematicians to come up with a figure on the odds of four generations of the one family sharing the same birthday, but no one was available.
But it is safe to say that baby Bronte is certainly one in a million, not just to her besotted mum and dad.
