JACK was ahead of the pack for the third consecutive year when it came to boy's names on the Border in 2015.
The moniker shared top spot with James in 2014, but with seven mentions in The Border Mail's 268 birth notices last year it was clearly ahead of Archie on four.
The girl's No.1 was divided between Ava and Sophie on five, ahead of Ella on four.
Lavington parents Scott Ronan and Nichole Sullivan had twins, Ava and Luke, on August 24.
The twins have siblings Aiden, 9, and Lily, 2, and a stepsister Jacklyn.
“Because we had Lily I wanted something that would fit in with Lily, a bit more old-fashioned and it was a toss-up between Ava and Ruby,” Ms Sullivan said.
“As soon as we said ‘Ava’ we loved it.”
The engaged couple, who delayed their wedding to February 2017 after falling pregnant, were less sure about Luke, which was recorded twice in the 2015 birth notices.
“I don't know where Luke came from,” Ms Sullivan said. “We wanted a strong name, he was going to be Luke or William, because William is Scott's middle name and a family name.”
It was family links which inspired Albury couple Chris and Rachael Toohey to name their first born Jack after he arrived on April 22.
“Jack goes back three generations, that was my father's father's name, so my grandfather's name, and we both liked Jack, so it was a good fit,” Mr Toohey said.
“He's a very smiley sort of baby and my grandfather was a bit of a poet, he told a few good yarns and recited unbelievable poetry.”
In addition to its latest hat-trick, Jack spent 2011 and 2012 as the second most popular boy's name and was the leading moniker five times in the century's first decade.
Among the more unusual boy's names to feature in this year's list were Frey, Lux, Macklan and Ryder.
Traditional names to make an appearance included Andrew, Edward, George, Thomas and William.
On the female side, rare names to appear were Aviva, Lylah, Sapphire and Tiahn.
Favourites of recent years to make the grade included Grace, Matilda and Olivia.
Charlotte, the name given to the English princess born to Prince William and the Duchess of Cambridge in May, was bestowed on three babies featured in The Border Mail's listing.
Ava, which gained popularity through American actress Ava Gardner, is a variant of the name Eve and its meaning is uncertain.
Sophie comes from the Greek word for wisdom.
Jack comes from John, but that name was not in The Border Mail's births in 2015.
Jack was among the most popular names in NSW in the 1920s but dived before it resurged in the 2000s.
