You could insert a new column D in Sheet2 and fill it with this
formula:

=A2&B2&C2

and copy this down. Similarly, insert a new column H and put this
formula in H2:

=A2&F2&G2

and copy this down. Then in Sheet1 D2 you can put this formula:

=IF(ISNA(VLOOKUP(B2&A2&C2,Sheet2!D:E,
2,0)),IF(ISNA(VLOOKUP(B2&A2&C2,Sheet2!H:I,2,0)),"n ot
present",VLOOKUP(B2&A2&C2,Sheet2!H:I,2,0)),VLOOKUP (B2&A2&C2,Sheet2!D:E,
2,0))

Copy this down as required.

Hope this helps.

Sheet 2 has the following
Surname * * *Forename * *Birthplace * *Nationality Forename Birthplace *
Natioanlity

Cardiff * * * Welsh
Ellis * * * * * * *David * * * * * Manchester *English * * David * * * *

match
i.e. Alan Jones Liverpool = Jones Alan Liverpool and returns the text
English in Sheet 1
