All of his family letters have the theme: "I want to see you."
He arrived as an immigrant in the United States on 16 December 1845 from Gavle, Sweden on the Neptunis. There was discussion in some letters of his upcoming trip in 1858. I've not found any evidence yet of his having made that trip. I have evidence of his visiting his family in July 1877 (sailing from Göteborg to NYC on 27 July 1877 and a family portrait taken with all 13 siblings together) and again in 1886 when he was honored at a ceremony as a past winner of a special swimming award.
On 26 August 1835, Eric won a laurel wreath in swimming at age 13. There was a booklet published about the swimming society UPSALA Simmsällskaps Matrikel. (1796-1859) that lists the various winners and describes the background of the organization. On 22 August 1886, there was some kind of special anniversary celebration of this race, Eric is listed on the program as Factory segaren E A Hellsten and I have the certificate he was given at the ceremony.
How she got to the US, I don't know. I've not found her in any published records for the US passenger arrival lists in the 1840's. Maybe she came through Canada and down the Hudson. I understand a number of companies recruited people in Ireland to settle in Canada to fill the boats going to Canada (the boats came back filled with lumber). If there are any immigration records coming into Canada or boat records, I've not found them. I'll take suggestions on other theories as to how she might have arrived here.
I also have no idea how she supported herself once she arrived before she married Eric. I have no idea if she came with anyone she knew or set out on her own. I've never found an official document about her other than her death certificate. The only reason I know where and when she as born is because it was hand-written on the back of her marriage certificate given them by the pastor, Abram Davis.
