Soru

In a family of seven members—$P, Q, R, S, T, U,$ and $V$—spanning three generations, there are two married couples. $P$ is the brother-in-law of $R$, who is the only daughter of $U$. $S$ is the father of $Q$ and $P$. $T$ is the maternal grandmother of $V$, and $Q$ is married to $R$. If $V$ is a male child of $Q$ and $R$, how is $V$ related to $U$?
