(6) Appropriate inquiry during the course of hearings in the case; and

(7) Any other reasonable means that are likely to identify relatives or other persons who have demonstrated an ongoing commitment to the child.

(c) All adult relatives of the alleged dependent child identified in a diligent search required by this Code section and all parents of a sibling of such child, when such parent has legal custody of such sibling, subject to exceptions due to family or domestic violence, shall be provided with notice:

(1) Specifying that an alleged dependent child has been or is being removed from his or her parental custody;
