Have a history teacher explain this----- if they can.?

History teacher is not required for this .this is fantastic co-incidence. you know some days will be there in the world that all new born will be girl children at a particular time and irrespective of their nation they will have an alphabet common in their name and they are unknown to anyone .never heard about anyone,even then it happens that's God and Nature's gift. it is called co-incidence.
