OK, let's back up again.  I'm still not completely clear what you have here.  
I think you have


Then you are trying to share files between each other by configuring various 
things to write directly to /home instead of /home/you or /home/your-wife

Is that right?

If so, that's very strange.  How do you even have write permission on /home?  
What is the permission on that directory?  It's supposed to be 755, and 
individual users are not supposed to be able to write to /home directly 
anyway.  I presume you've changed this.

I guess you can do it that way if you insist, but it seems messy and difficult 
to manage safely.  Why not create a shared directory for the two of you with 
775 permissions?

Other posts that I missed previously already explained about setting your 
umask in various places.  With the right umask (0000 would work, or you could 
be more restrictive), and a directory you can both access it should be 
possible to do what you want.

Something like this:

[root@your-box] /home
->mkdir shared-directory-demo
[root@your-box] /home
->chmod 755 shared-directory-demo
[root@your-box] /home
->chown root:your-family-group shared-directory-demo
[root@your-box] /home
->ls -ld shared-directory-demo/
drwxrwxr-x    2 root     your-family-group     4096 May  9 21:04 
[root@your-box] /home
->cd shared-directory-demo/
[root@your-box] /home/shared-directory-demo
->su you
[you@your-box] /home/shared-directory-demo
->umask 0000
[you@your-box] /home/shared-directory-demo
->touch foo
[you@your-box] /home/shared-directory-demo
->ls -l foo
-rw-rw-rw-    1 you   you          0 May  9 21:04 foo
[you@your-box] /home/shared-directory-demo
->cd ..
[you@your-box] /home
[root@your-box] /home/shared-directory-demo
->su your-wife
[your-wife@your-box] /home/shared-directory-demo
->umask 0000
[your-wife@your-box] /home/shared-directory-demo
->touch foo
[your-wife@your-box] /home/shared-directory-demo
->ls -l foo
-rw-rw-rw-    1 you   you          0 May  9 21:05 foo

You've made a directory, chowned it to your-family-group, set it to 775 so the 
group can write there.  Then when you set your umask to 0 and create a file, 
your wife can then modify the same file, even though you still own it.

This seems like what you want.  It would probably be better to use a umask of 
0007 instead, so you still have *some* control.  (I should have used that in 
the above example, but I'm too lazy to go back and re-do it.  :)

Anyway, is this even helpful, or are you trying to do something I still don't 
quite understand?
