Group / Union Statement - Pull Unique Records From A Large Table

I am trying to use SQL to pull unique records from a large table. The table consists of people with in and out dates. Some people have duplicate entries with the same IN and OUT dates, others have duplicate IN dates but sometimes are missing an OUT date, and some don’t have an IN date but have an OUT date.

What I need to do is pull a report of all Unique Names with Unique IN and OUT dates (and not pull duplicate IN and OUT dates based on the Name).

I have tried 2 statements:

#1:
SELECT DISTINCT tblTable1.Name, tblTable1.INDate
FROM tblTable1
WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#))
GROUP BY tblTable1.Name, tblTable1.INDate
ORDER BY tblTable1.Name;

#2:
SELECT DISTINCT tblTable1.Name, tblTable1.INDate
FROM tblTable1
WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#))
UNION SELECT DISTINCT tblTable1.Name, tblTable1.INDate
FROM tblTable1
WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#));

Both of these work great… until I the OUT date. Once it starts to pull the outdate, it also pulls all those who have a duplicate IN date but the OUT date is missing.

Example:

NameINOUT
John Smith1/1/20141/2/2014
John Smith1/1/2014(blank)

I am very new to SQL and I am pretty sure I am missing something very simple… Is there a statement that can filter to ensure no duplicates appear on the query?
