class from a Dictonary?

[JustSomeGuy1962]

Dictionary<String, List<String>> FamilyNameSiblingList;

Can I make a type or class out of this?

It's not really clear what you're asking for. That code is only part of a variable declaration. Can you please provide a FULL and CLEAR explanation of what you're trying to achieve?
