• Inheritance of property through uncle

Respected members/Sir,
 
I have gone through the forum and read few articles for my situation i am getting contradictory info so help me with all possible advice below is the situation
Mr.A(Great Grand Father) had 5 children 3 girls and 2 boys, all born pre-independence and all passed away before 2002 Mr.A made a Gift Deed and passed on his own earned assets to both sons
all the 5 got married the 3 sisters and 2 son
now the 2 sons are B and C,
B had 2 sons and C died without issues, all the sisters in this case have their lineage.
B with sons died and since it joint family C got to be the executor and every thing was handeld solely by him 
C passed without legal Heir's and both widowed passed as well
 
Now my question is in this scenario can the daughters son's have any claim on this property
and Mr.B's Son who also have passed away can their heirs claim this
Kindly Clearify since the people passed away before the 2005 amendment.
 
I am a Party and am the grandson for Mr.B
Mr.A, Mr.B, and Mr,C and all the three sisters have passed away before 2001
 
i am no legal expert but is 2005 amendment applicable retrospectively.
i am not very well to do hence i post the query here first, and a favorable answer or a way out is what i am expecting.
