Possibly Children of Elias Mills of Warren County and Lucas County, Iowa

All of these photos were given to me by another Mills relative. Based on the area of the photo studio, and other pictures I have of Elias Mills and his family, it's possible these are children of Elias Mills or other relatives. Photos taken around 1890's at the time cabinet card photos were common, also judging from the identified photo below of his sons Herman and Jesse. 

(Above) If this is Elias Mills son, this could be Abel Edwards Mills or Norvel Rafe Mills. If the photo was taken around 1890/91.

Back of photo reads: Jesse Irvan Mill and Herman Everette Mills sons of Elias Mills

(Above) Herman Mills was born 1881, which may place this photo around 1890/91 if he was around 9 or 10 year old and his brother Jesse Mills was born 1884 and he appears to be around 6 years old in this photo.
