Immigrant Ships To America/Ships/Immigrants/caveats

''These data are based on the work of Amadeus Johnson, 1911. It is certain that additional immigrants to New Sweden were not captured in Johnson's lists. Also, some individuals shown made several trips back and forth between Sweden and New Sweden, and so appear multiple times. Some individuals returned to Sweden after a greater or lesser period, and left no descendants in New Sweden. (These later have not been marked as such, though this should eventually be accounted for.) Some individuals died on the trip over, or immediately after arrival;  in some cases their families are known to have remained in New Sweden. In other cases, they probably left no issue.''

Johnson, 1911 built these data, at least in part on colony records, rather than on formal ship lists. In some cases he has inferred arrival on certain ships at certain times, simply because he had no earlier record for them. In some cases he may have overlooked earlier records, leading to a false inclusion on a ship list. For example, Johan Gustafson is showing arriving in 1643 on the Swan, and again in 1654 on the Orn. This does could mean either of the following a) Gustafsson made two trips to New Sweden, first in 1643, and second after returning briefly, in 1654, b) he made only one trip in 1643, and Johnson's interpretation of the records resulted in his erroneous inclusion of Gustafsson on the Orn, and c) these are two different persons.''
