 * Surprising Relationship

Solution
A man $G$ marries the mother of a woman $H$, while $H$ marries the father of the $G$.

Of these marriages, $G$ became Edwin's father and $H$ became Mr. Tomkins' mother.

Then $A$ is then the half-brother of Mr. Tomkins, and $B$ is the half-brother of Edwin.

Thus Mr. Tomkins is the uncle of Edwin, who is the nephew of Mr. Tomkins, and Edwin is the uncle of Mr. Tomkins, who is the nephew of Edwin.
