Getting Indirect parents

I have following different tables

LeafChilds

ChildId, ChildName

1, Child1

2, Child2

Group

GroupId, GroupName

1, Group1

2, Group2

3, All

GroupChildMapping

GroupId, ChildId

1, 1

2, 1

2, 2

GroupGroupMapping

GroupId, ParentGroupId

1, 3

1, 3

I am looking for query to find indirect parents for LeafChilds.In above example - child1 is in Group1 and Group1 has parent group as ALL. So indirectly child1 is in ALL group as well.

OUTPUT

Child1, Group1

Child1, ALL
