Adventures in proofreading: too many Milners

My apologies in advance to anyone named Milner.  I don't mean that there are too many of you.

In the late eighteenth and early nineteenth centuries, there are at least five different Milners putting out religious controversial material:

• The noted mathematician Isaac Milner;
• Isaac's brother, Joseph Milner;
• Thomas Hughes Milner, active in the mid-Victorian period;
• John Milner, an important Catholic controversialist;
• and John Milner, MA, who did a potted edition of the Book of Martyrs, called An Universal History of Christian Martyrdom.

I was cheerfully indexing along, working my way through Milner, when I was brought up short by the appearance of Thomas Hughes on the page.  Because Thomas would have been a little too green behind the ears to be publishing anything in the 1830s.  Some double-checking revealed that I really meant Joseph Milner.  I scolded myself sternly and continued on.

Next: the case of two Johns.  I had a reference to an "evangelical John Milner," but then again, there was the Catholic John.  Were there really two John Milners, or had I completely screwed up mistyped once again? After all, John #1 was doing a good imitation of being an evangelical.  Still, I checked my source, and found that John Milner (the evangelical) was not John Milner, but actually the very short-lived Francis William Blagdon.  This, however, was interesting for another reason: why choose "John Milner, MA" as the pseudonym under which to publish the aforementioned potted Book of Martyrs? Was it possibly a snark aimed in the direction of the real John Milner, who became a Bishop in 1803?  Further noodling about reveals that, in fact, it very likely was.
