The most popular baby names in Daventry last year were Harry for boys and Mia for girls, according to the Office of National Statistics.
Last year 824 babeis were born in the area, 429 boys and 395 girls.
Parents in Daventry didn’t follow the national baby-naming trend for boys, with Oliver failing to make the top spot.
Olivia, the nation’s favourite name for girls, also didn’t top the charts for Daventry parents last year.
The second most popular name for baby boys was William, followed by Jacob in third.
For girls, second place was a two-way tie between Isabella and Olivia.
Nick Stripe, of the ONS, said: “Although Oliver and Olivia remained the most popular baby names in 2017, some fascinating changes took place beneath them.
“Leo entered the boys’ top 10 for the first time, whilst Hunter rocketed into the top 100, also for the first time, reaching number 78.
“Sarah, the most popular name for baby girls throughout much of the 1970s and 1980s, dropped out of the top 100 for the first time since our records began in 1904. Brand new entries into the top 100 for girls include the names Aurora and Hallie.”
