Another solution without recursion...

var result = FamilyToEnumerable(familyRoot)
                .Where(f => f.Name == "FamilyD");


IEnumerable FamilyToEnumerable(Family f)
{
    Stack stack = new Stack();
    stack.Push(f);
    while (stack.Count > 0)
    {
        var family =  stack.Pop();
        yield return family;
        foreach (var child in family.Children)
            stack.Push(child);
    }
}
