Extract Data From Multiple Tables Into One Table

Let us suppose I've 3 tables in which 2 columns data are same in all 3 tables & rest fields are distinct

Table 1 :
ID1 ID2 Gender Code towncode
1 12 1 234 1234
2 13 2 543 5463
89 187 1 125 N21Q

Table 2 :
ID1 ID2 Relation Name DOB
1 12 13 XYZ 21/01/1967
1 12 1 QAS 01/10/1987
1 12 2 NHS 09/12/2001
2 13 1 NHG 10/01/1987
2 13 2 GHS 16/12/1999
89 187 2 KJA 31/03/2000
89 187 1 KLA 09/11/1986
89 187 5 KOP 19/12/2001

Table 3 :
ID1 ID2 Period Date
1 12 1 01/01/2011
2 13 1 01/01/2011
89 187 2 01/01/2011

I want result as :
ID1 ID2 Gender Code towncode Relation Name DOB Period Date
1 12 1 234 1234 13 XYZ 21/01/1967 1 01/01/2011
1 12 1 234 1234 1 QAS 01/10/1987 1 01/01/2011
1 12 1 234 1234 2 NHS 09/12/2001 1 01/01/2011
2 13 2 543 5463 1 NHG 10/01/1987 1 01/01/2011
2 13 2 543 5463 2 GHS 16/12/1999 1 01/01/2011
89 187 1 125 N21Q 2 KJA 31/03/2000 2 01/01/2011
89 187 1 125 N21Q 1 KLA 09/11/1986 2 01/01/2011
89 187 1 125 N21Q 5 KOP 19/12/2001 2 01/01/2011

May be some duplicate entry of same record is available in Table 1.
