In the 1840s, Joseph Smith adopted the idea (to some degree) that the Book of Mormon occurred in Central America. This is likely because he received a copy of the book Incidents of Travel in Central America in 1841.

Book of Mormon parallels to 1800s thought
Richard Bushman, well-known Mormon historian, stated:
… there is phrasing everywhere–long phrases that if you google them you will find them in 19th century writings. The theology of the Book of Mormon is very much 19th century theology, and it reads like a 19th century understanding of the Hebrew Bible as an Old Testament …
And Blake Ostler, another well-known Mormon scholar, has noted:
Many Book of Mormon doctrines are best explained by the nineteenth-century theological milieu.
In many ways, at least, the theological debates, doctrines, and themes advanced in the early 1800’s milieu seem to be reflected—sometimes quite substantially—in the Book of Mormon.
Compilation of these:
Also. Moroni, son of Mormon, finishes the record of his father Mormon by quoting a message of Jesus Christ to “his disciples who should tarry.” Mormon says, in Mormon 9:22–24:
22 For behold, thus said Jesus Christ, the Son of God, unto his disciples who should tarry, yea, and also to all his disciples, in the hearing of the multitude: Go ye into all the world, and preach the gospel to every creature;
23 And he that believeth and is baptized shall be saved, but he that believeth not shall be damned;
24 And these signs shall follow them that believe—in my name shall they cast out devils; they shall speak with new tongues; they shall take up serpents; and if they drink any deadly thing it shall not hurt them; they shall lay hands on the sick and they shall recover;
The book of Mark ends with these verses:
15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
17 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
18 They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
The book of Mormon is using the ending of Mark, something that is widely accepted by scholars to be a later addition.
E. P. Gould wrote:
… the internal evidence for the omission is much stronger than the external, proving conclusively that these verses could not have been written by Mk. The linguistic differences alone are enough to settle this,—enough to show, even if we had Mk.’s autograph, that they were not original with him, but copied directly from another source.
there are in all 163 words in this passage, and of these, 19 words and 2 phrases are peculiar, not occurring elsewhere in this Gospel. There are 109 different words, and of these, 11 words and 2 phrases do not occur elsewhere in this Gospel. …
But the argument from the general character of the section is stronger still. In the first place, it is a mere summarizing of the appearances of our Lord, a manner of narration entirely foreign to this Gospel. Mark is the most vivid and picturesque of the evangelists, abbreviating discourse, but amplifying narration. But this is a mere enumeration. The first part of the chapter, relating the appearance of the angels to the women, is a good example of his style, and is in marked contrast to this section.
