Get all Title Block Family Types in the project

How do I get all Title Block Family Types in the project?

[viktor_kuzev]

Cloclwork has a node “All Family Types of category”

Well you have the instance elements so now you just need to get the FamilyType from the instance. There are a few nodes that will do this but the first in my head is Element.ElementType.
