Pencil Drawings Anne H. K. Cleaver?

Ihave two smaller framed pencil drawings by what looks to be an Anne H.K. Cleaver. They are numbered and titled. I've not been able to find out anything about the artist online. The first one says "By The Sea" and is numbered 14/100. The second one is titled "Lydia" and is numbered 3/50. Anyone know who this artist was/is? The drawings are very small, I would say 2-3" around and are matted and framed in a 6"x6" frame. The Lydia one strikes me as slightly different because the drawing itself appears to be slightly raised.
