SQL Server 2012 :: Filter Duplicates Based On String?

CREATE TABLE #Names
( ID INT IDENTITY(1,1),
NAME VARCHAR(100)
)
INSERT INTO #Names VALUES ('S-SQLXX')
INSERT INTO #Names VALUES ('S-SQLXX.NA.SN.ORG')
INSERT INTO #Names VALUES ('S-SQLYY')
INSERT INTO #Names VALUES ('S-SQLYY.NA.SN.ORG')
INSERT INTO #Names VALUES ('S-SQLCL-HR')
INSERT INTO #Names VALUES ('S-SQLCL-MIS')
SELECT * FROM #Names

--I want to filter out S-SQLXX.NA.SN.ORG because S-SQLXX.NA.SN.ORG is a duplicate of S-SQLXX eliminating .NA.SN.ORG from it.

--I want to filter out S-SQLYY.NA.SN.ORG because S-SQLYY.NA.SN.ORG is a duplicate of S-SQLYY eliminating .NA.SN.ORG from it.

--However I want to keep S-SQLCL-HR and S-SQLCL-MIS in my list of names as they do not have .NA.SN.ORG as a part of their name

--I want ONLY these returned IN the SELECT

SELECT * FROM #Names WHERE ID IN (1,3,5,6)
DROP TABLE #Names
