Doesn’t it make sense to you that a “principle ancestor” would have left some mtDNA around?

*HYPOTHESIZED LOCATIONS OF BOOK OF MORMON LANDS. Two issues merit consideration in relation to possible external correlations of Book of Mormon geography. What is the official position of the Church, and what are the pervading opinions of its members?
In early Church history, the most common opinion among members and Church leaders was that Book of Mormon lands encompassed all of North and South America, although at least one more limited alternative view was also held for a time by some. The official position of the Church is that the events narrated in the Book of Mormon occurred somewhere in the Americas, but that the specific location has not been revealed. This position applies both to internal geographies and to external correlations. No internal geography has yet been proposed or approved by the Church, and none of the internal or external geographies proposed by individual members (including that proposed above) has received approval. Efforts in that direction by members are neither encouraged nor discouraged. In the words of John A. Widtsoe, an apostle, “All such studies are legitimate, but the conclusions drawn from them, though they may be correct, must at the best be held as intelligent conjectures” (Vol. 3, p. 93).
Three statements sometimes attributed to the Prophet Joseph Smith are often cited as evidence of an official Church position. An 1836 statement asserts that “Lehi and his company…landed on the continent of South America, in Chili [sic ], thirty degrees, south latitude” (Richards, Little, p. 272). This view was accepted by Orson Pratt and printed in the footnotes to the 1879 edition of the Book of Mormon, but insufficient evidence exists to clearly attribute it to Joseph Smith (“Did Lehi Land in Chili [sic]?”; cf. Roberts, Vol. 3, pp. 501–503, and Widtsoe, Vol. 3, pp. 93–98).
In 1842 an editorial in the Church newspaper claimed that “Lehi…landed a little south of the Isthmus of Darien [Panama]” (T&S 3 [Sept. 15, 1842]:921–22). This would move the location of Lehi´s landing some 3,000 miles north of the proposed site in Chile. Although Joseph Smith had assumed editorial responsibility for the paper by this time, it is not known whether this statement originated with him or even represented his views. Two weeks later, another editorial appeared in the Times and Seasons that, in effect, constituted a book review of Incidents of Travel in Central America, Chiapas and Yucatan, by John Lloyd Stephens. This was the first accessible book in English containing detailed descriptions and drawings of ancient Mayan ruins. Excerpts from it were included in the Times and Seasons, along with the comment that “it will not be a bad plan to compare Mr. Stephens´ ruined cities with those in the Book of Mormon: light cleaves to light, and facts are supported by facts. The truth injures no one” (T&S 3 [Oct. 1, 1842]:927).
In statements since then, Church leaders have generally declined to give any opinion on issues of Book of Mormon geography. When asked to review a map showing the supposed landing place of Lehi´s company, President Joseph F. Smith declared that the “Lord had not yet revealed it” (Cannon, p. 160 n.). In 1929, Anthony W. Ivins, counselor in the First Presidency, added, “There has never been anything yet set forth that definitely settles that question [of Book of Mormon geography]…. We are just waiting until we discover the truth” (CR, Apr. 1929, p. 16). While the Church has not taken an official position with regard to location of geographical places, the authorities do not discourage private efforts to deal with the subject (Cannon).
The unidentified Times and Seasons editorialist seems to have favored modern Central America as the setting for Book of Mormon events. As noted, recent geographies by some Church members promote this identification, but others consider upstate New York or South America the correct setting. Considerable diversity of opinion remains among Church members regarding Book of Mormon geography; however, most students of the problem agree that the hundreds of geographical references in the Book of Mormon are remarkably consistent—even if the students cannot always agree upon precise locations.

The debate goes back a long way and much was speculation. There are quotations from previous general authorities about this from a long time ago. Assumptions are never doctrine.
