In your model use define __str__ method to name1. Then django admin will
use name1 in dropdown box.

This really depends on the structure of your models. In this case you will
most likely have a ForeignKey in one of your models; if the referenced
model has an __str__() method, the admin site (and also any other forms)
will display names instead of the text "OtherModel object".

The two models from msaccess are linked by name field, not id.
Can I like by name field in django and not use id?

It is possible, but in an SQL database it may become ineffective. For this,
you will have to make the name field unique, and put an index on it
(uniqueness also creates an index, by the way).
For the admin site to display names, though, you still have to define the
__str__() method that does only
Thanks, I will look into adding id
If I just do this, clinician = models.ForeignKey(Clinician)

If you go with the current solution, you will have to add the to_field
keyword argument to ForeignKey:
clinician = models.ForeignKey(Clinician, to_field='name')

You need to set few additional attributes in your foreign key.
First you have to use db_column='', and to_field=''
db_column value would be column name in your table that holds foreign key.
I guess this would be 'name2' in your model that reflects table2
to_field would be reference in field in a
