Who is "this man"?

Brothers and sisters, I have none, but this man's father is my father's son.

So who is "this man"?

Don't google it, and show your working out.
I was convinced that I had it right but after much thinking realised the correct answer...

looking in a mirror?

We shall see.

Is it his son?

Hooray for AD.

He's talking about his son.

My fathers son is me.

So it reads as Brothers and sisters, I have none, but this man's father is me.

I always thought the answer was himself, until the other day. Yes, "this man" refers to the speaker's son.

Frankly it could be almost anyone in Norfolk.

Or Bolton.

Is it Nicholas Lyndhurst?

Is it Magoo ?
