Access: show only one instance of a name

i have a table with multiple instances of a name.

example:

lastname    firstname       fullname           dob
smith          john               smith, john        01-01-1901
george        albert            george, albert    01-02-1905
smith          john               smith, john        02-09-1956

i want a query that will display the name only once..

example:

lastname   firstname       fullname
smith         john               smith, john
george        albert            george, albert

thanks!!
