 I think I found Dugald McBride and Sarah Paterson (not helped by Ancestry's transcription of their name which I'll leave as indexed!):
Dugd McVorgde    50, Subr (?) Tenant
Sarah McVorgde    50
Margt McVorgde    15
Neil McVorgde    13
Address:  Teretigan, Kilberry Argyll
I have checked on the SP index (not showing on FreeCen - no idea why as they are supposed to be 100% for Argyll) and found this likely corresponding entry:
1841   MCBRYDE   SARAH   F   50   KILCALMONELL AND KILBERRY   /ARGYLL   516/00 006/00 015
Now, from personal experience with my MacDonalds in Argyll  

, Sarah and Marion are sometimes interchangeable (no idea why). I found these entries yesterday on SP's OPR index for births/christenings which now make more sense with the above potential 1841 entry:
1   16/12/1823   MCBRIDE   KATHERINE   DUGALD MCBRIDE/MARION PATERSON FR475   F   Kilcalmonell and Kilberry   /ARGYLL   516/ 0020 0037   
2   20/04/1834   MCBRIDE   MARY   DUGALD MCBRIDE/MARRION PATERSON FR632   F   Kilcalmonell and Kilberry   /ARGYLL   516/ 0020 0336
Given the ages for Dugald and Sarah born c. 1787-91, we also have their marriage on the OPRs in North Knapdale on 29 Jun 1821. Makes sense.
Who they are and how they connect to the other two families still no idea  

Regards.

FreeCen do have them. Original writing must be awful. It is also a complete listing of the household which looks to have gone over to two pages:
MCRORGDE Dugald       50 Sub Tenant         
MCRORGDE Sarah       50               
MCRORDGE Margaret     15               
MCRORGDE Neil       13           
MCRORDGE Chirsty   9   b. Argyllshire        
MCRORDGE Mary       7    b. Argyllshire        
MCALPINE Mary       60 Merchant b. Argyllshire
Address: Teretigan, Kilberry
There is a note for the household regarding legibility of surname. Also, the first few entries do not have birth county details, again I would imagen due to illegibility.
