This is one reason I consider the BOM unreliable. All of these folks in it other than the Biblical characters are no place to be found in history or archeology. There's nobody around in history with BOM geneologies traced to them.
My point exactly. I don't think you grant the Bible the same treatment. Here it is not the genealogy that proves anything, but how verifiable the genealogy is. That's the point.
I suggest you take a good look at the OT books and note the frequency and quantity of this material in it. It's hard to get a handle on how much, since it is mostly a lot of short family statements whenever someone is mentioned. These are frequent in much of the OT and scattered widely enough that the enormity of them is easily un-noticed.
I've read all the historical books of the OT many times, and I think I have a pretty good grasp of the frequency and quantity of its genealogies, even in the sense you're talking about. I'm not so sure you have the same grasp on the Book of Mormon. I haven't read the Book of Mormon all the way through, and I don't want to, but its genealogical references are
very similar to the Bible. About 1/3 of the BOM is plagiarization from the Bible, anyway.
J.S. was remarkably familiar with the Bible. It's pretty obvious, at least to me, that he had been in church, read the Bible, and had lots of questions, which he attempted to answer in the BOM. There was enough familiarity to write in a style similar to the KJV, including always providing genealogical data, just like in the OT. (Unfortunately, he wasn't familiar enough with history to do it well, and he had synagogues before synagogues were invented, and he used a Greek name, Philip, for a brother of his apostles in a situation, supposedly in America, where there could have been no Greek influence.)
