Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

The Wizard found an image of Bookhout's parents, and this is his father on the left. 

And that, of course, is James Bookhout on the right.  And yes, they look like they could be father and son. This is what the Wizard wrote:

The ancestry site had a photo of Bookhout's parents (attached): the very image of frumpish Victorian respectability. 

It hints at a strict upbringing. You can see the resemblance in the father: the close-set eyes and slim nose.
