Linda Ella (Trover) Hackett Barris's FAMILY

The woman with glasses has been identified as Linda Ella (Trover - maiden name) Hackett - first married name Barris - 2nd married name. The children are her children from 2nd husband, Joshua Wright Barris. Some died young. The man in the middle - we aren't sure if this is her son from her first marriage, Harry Hackett, or her husband, Joshua Wright Barris as the young man doesn't look that old. Should you have HACKETT, BARRIS or TROVER in your tree and can identify this photo, we would be anxious to hear from you and you can respond to [contact link]
This family is from Beaver County, PA and this is the late 1800's.

Is the man in the middle HARRY HACKETT or JOSHUA WRIGHT BARRIS? or is Harry the man in the back row?
