Blood Relations

Meera's grandfather has only two sons, Jayesh and Vijay, and no daughters. Dakshit is the grandfather's only grandson. Meera's mother Sheetal is married to Jayesh (Vijay is her brother-in-law), and their daughters are Meera and Mamta. So the only grandson Dakshit must be the child of Vijay and his wife Sunita, which makes Dakshit Sunita's son.

Mamta is Meera's only sister, so both are daughters of Jayesh and Sheetal. Vijay is Jayesh's brother, which makes him Mamta's uncle. Mamta is therefore Vijay's niece.

The third generation consists of the grandfather's grandchildren. Jayesh and Sheetal have two daughters, Meera and Mamta, while Vijay and Sunita have the only grandson, Dakshit. That gives three children in Meera's generation.
