It took a substantial amount of time to work out who each of these people were as there is an “extra” male person than would be present if this were a photograph of just Lemuel and his siblings. These photos seem to be a “welcoming” of Carrie into the “Miller Family” sometime around her marriage to Lemuel on 2/3/1916. The best-guess as to who each person is, specifically, is listed on the above photograph.

Unsure - Possibly Gertie & Carrie
Gertie & Cora Miller
