Not enough info about your layers but, in general, I *would* create a new class for the two fields - but farther down the hierarchy and not at the repository level.
You can then retrieve the full rows and use Linq to select into the smaller class. e.g:
var shortRecords = fullRecords.Select(x => new ShortRecord {Age = x.Age, Name = x.Name});
Returning an object jeopardizes type safety and can quickly become messy.....
