Just a quick point...
"SVENSKARNA I NYA ZEELAND" by Sten Aminoff is notoriously inaccurate. As he had free rein at both NZ Archives and the Swedish National Archives the information from each one is usually pretty accurate. However when he came to linking records from one country to the other there often seemed to be a bit of guesswork involved, at least that's how it looks to me (and to lots of others by all accounts).
On the other hand, if I had jumped ship I would definitely change my date and place of birth when filling in any official forms (marriage/naturalisation). Might account for the age discrepancy.
As an example, the WW1 Attestation for Erik Gustaff's son, also called Erik Gustaff, says his Dad came from Ireland!!!

Here are the names of some of the children and grandchildren of Erik Gustaff ANDERSON. Do any of these names ring bells in your family history...

His name is Peter Anderson/Andersen and he was born about 1832.
How did you find his birth year of 1832-ish.

I have been given the Swedish family report also.
Is this a report you commissioned from a Swedish genealogist - or something similar. If so, what did they come up with.

I don't know if he [Peter] had any siblings
[...]
Also, it is said that Petter and his brother Erik jumped ship together, but my Peter was already married at the time that Erik jumped ship.
A bit confused :-)
When you say
"it is said that Petter and his brother Erik jumped ship together" is this a family story or something from the report.
And you say
"my Peter was already married at the time that Erik jumped ship". In reply #17 Ian says that Erik jumped ship in 1872. Peter's marriage to Petrine wasn't until 1874.
