First Shall Be Last
Angie, Carla, Colt, Eric, June, & Oliver are a weird group of friends. Why? Their last names are Angie, Carla, Colt, Eric, June, & Oliver, but not necessarily in that order. Can you figure out their last names? (Someone can have the same first and last name)
1. One of the people with Oliver in their name also has Angie
2. Someone's initials are C.C.
3. Eric and Oliver share no names
4. June & Angie don't have Oliver or Carla as their last name
5. June & Colt share no names
6. Carla's name has 4 syllables
7. At most one person has the same first and last name
8. Angie's last name is female
Clarification:
Angie - Female; 2 Syllables
Carla - Female; 2 Syllables
Colt - Male; 1 Syllable
Eric - Male; 2 Syllables
June - Female; 1 Syllables
Oliver - Male; 3 Syllables

Answer
June EricEric Colt
Colt Oliver
Oliver Angie
Angie June
Carla Carla
Step 1: Oliver Angie
According to clue 1, we know there is either an Angie Oliver or an Oliver Angie; however from clue 4, we know there can't be an Angie Oliver, therefore we know that Oliver's last name is Angie.
Step 2: Colt Oliver
The first name that has Oliver as a last name can be solved with the process of elimination. It can't be June or Angie as per clue 4. It can't be Oliver as we already labeled his last name. It can't be Carla as "Carla Oliver" has 5 syllables, and it can't be Eric since he doesn't share any names with Oliver.
Step 3: Carla Carla
In clue 2 we know there is one of the following:
Colt Colt
Colt Carla
Carla Colt
Carla Carla
Since we already know Colt Oliver, we know Carla is the one with the last initial "C." "Carla Colt" only has 3 syllables, so therefore, we get Carla Carla.
Step 4: June Eric
For June's last name, there are 3 options: Colt, June & Eric. Clues 7 and 5 eliminate June & Colt respectively.
Step 5: Final 2
Angie's last name can't be Colt as per clue 8, so that leaves Angie June & Eric Colt.

I do love these, and this was a particularly good one, in my opinion. Easy enough to be able to write down the names without a whole grid or anything, but tough enough to take a few minutes. Nice job!
