Question

The example below shows the result for every Name that has a connection to Table2 (Table1 TId is PK, and TId in Table2 is the FK).

SELECT T1.Name, T1.Address
FROM Table1 AS T1
    INNER JOIN Table2 AS T2
    ON T1.TId = T2.TId;

I want a list of all Names from Table1 that have NO corresponding row in Table2. The other way around so to speak. How could this be done?

You need to use an Outer Join as shown below:

SELECT T1.Name, T1.Address
FROM Table1 AS T1
     LEFT OUTER JOIN Table2 AS T2 ON T1.TId = T2.TId
WHERE T2.TId IS NULL
