NEW YORK: Have you noticed that more siblings nowadays share the same first initial? It is not a Kardashian sisters' trend but having the same first initial for siblings is now a norm among parents, finds a Facebook study.

Data scientists found that Facebook siblings in the US of all ages had a high likelihood of having the same first initial.

During the study, data scientists analysed the decisions parents make when giving their children unique names.

They compared users listed as siblings with random pairs of people with the same name.

The study found that siblings have an 11 percent chance of having a name with the same first initial compared with seven percent of random Facebook users.

Twins have an even higher chance of being named with the same first initial, said data scientists on a Facebook blog.
