 * Surprising Relationship

Solution
The simplest way for this to happen is as follows.

Two men, $A$ and $B$, married the mother of the other.

Of these marriages, $A$ became Edwin's father and $B$ became Mr. Tomkins' father.

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.
