I have a little info on your Caleb and his brothers Isaac and Alexander Feris while they were in York County, South Carolina.
It appears that their parents may have been John Feris (died 1 Feb 1804 Rocky Allison Creek, York Co., SC) and his wife Ann (Zellefrow?)(died 7 June 1803 Rocky Allison Creek, York Co., SC)(both buried at Ebenezer Presbyterian (now A.R.P.) Church now in Rock Hill, York Co., SC).
I don't have any record suggesting the names of their wives, however. Just their Revolutionary War records and some court records and deed records.
There were possibly two other brothers John and Levi.
