Script needed to delete to the list of files in a directory based on last created & delete them

Hi

My directory structure is as below.

dir1, dir2, dir3 

I have the list of files to be deleted in the below path as below.

/staging/retain_for_2years/Cleanup/log $ ls -lrt
total 0
drwxr-xr-x    2 nobody   nobody          256 Mar 01 16:15 01-MAR-2015_SPDBS2
drwxr-xr-x    2 root     system          256 Mar 01 16:18 01-MAR-2015_DBSRP3
drwxr-xr-x    2 nobody   nobody          256 Mar 01 23:56 01-MAR-2015_DBSRP1
drwxr-xr-x    2 nobody   nobody          256 Mar 02 06:40 02-MAR-2015_DBSRP1

and inside there directories it has files as below - based on directory name.

home_list_of_files_to_be_deleted.out
db_ist_of_files_to_be_deleted.out
var_ist_of_files_to_be_deleted.out

I want to have a script which can read the content of these files and delete the files inside them and log what was deleted.

What have you tried so far?

I've never seen a directory structure like dir1, dir2, dir3 . Is it more like

parent_dir/dir1/dir2/dir3/

or

parent_dir/dir1/
parent_dir/dir2/
parent_dir/dir3/

or even completely different?
And - what content of which files do you need to read?
