Ok, revised for the new information presented.

Assumptions - your data is laid out in A, B, C and D as you indicated and
starts in row 1 and continues to row 100.
To get the matching names, use this in E1 and drag down:
=IF(ISNA(MATCH(A1,C$1:C$100,0)),"",INDEX(C$1:C$100,MATCH(A1,C$1:C$100,0),0))
then in at F1 to get the value associated with the matched names, use this
and drag down:
=IF(ISNA(MATCH(A1,C$1:C$100,0)),"",INDEX(D$1:D$100,MATCH(A1,C$1:C$100,0),0))

We should stress that the names in BOTH lists should be in alphabetical order
as you said they were in your original question, otherwise your results may
not be as desired.  Here's list of things as I set them up to test the
equations:
 A            B              C              D              E              F
(E & F from formulas)
Adria    15    Adria    7    Adria    7
Harvey    33    Harvey    12    Harvey    12
Jenna    7    Jerry    18       
Jerry    21    Lee    21    Jerry    18
Lee    404    Mary    33    Lee    21
Mary    18    Ralph    83    Mary    33
Morris    83    Scoda    404       
Ralph    501    Tom    501    Ralph    83
Scoda    12            Scoda    404
Tom    66            Tom    501

Say your first list is in A1 to B100,
And your second list is in D1 to E100.

Enter this formula in F1:

=IF(ISNA(MATCH($A1,$D$1:$D$100,0)),"",INDEX($D$1:$E$100,MATCH($A1,$D$1:$D$10
0,0),COLUMNS($A:A)))

Copy across to G1,
Then select *both* F1 and G1, and drag down to copy.

Really no need for anything to be sorted.
