Were can I get information about Italian Queen Margharita and her children?

She started her reign in the early 1800 s, I would like to know the names and ages of all her children during 1883 and 1884.
Thanks.

Apparently she was quite fond of cocktails.
During a holiday in Mexico in 1876 she invented a drink which still bears her name today.
Cheers my dears!
