Tell me anything about the kelly family

They are European singers
I like some of their old songs

Which Kelly family? My former sister-in-law was married to a man whose last name was Kelly. There are possibly millions of Kelly's out there. Can you provide at least the location?

Their last name is kelly

The last name of Kelly, how many are there in the world? I looked in the phone book here and there are 35 families with the Kelly last name. If the OP has a location or point of origin or even some dates, it might help.

Kelly, Smith, Jones, very common names. We need something more to go on.

Oh he's asking for the genealogy
