I'd insert two new columns before the list, say A and B. In the first data
row in B, say B2, I'd enter a formula that combines the first and last names
to create a field the uniquely identifies each record: =C2&D2 and copy it
down to all records. Next in A2 enter this formula: =IF(B2=B1,A1+1,1) and
copy it down.

Change Calc mode to Manual if it's not. Then sort by column A. All the
"2"s are the records you want. Select the range from the first 2 to the
last, copy, and paste it in a new sheet.
