Alvie Foster, James Allen Foster, ? Foster

We don't know where and when this picture was taken. We do know the man in the middle is James Allen Foster. The fellow to the left we believe is Charles Alvie Foster, his son. The lady to the right is sort of a mystery, it may be one of his daughters-either Sarah Lee Foster or Edna Foster. We are trying to get any and all info. on James Allen Foster who moved to Missouri from KY-he lived in East Prairie, then Mill Spring, then St. Louis city. Please email me if you know this man, he is my gr. grandfather.
