It looks like my Olaf was born in 1837 and according to the 1900 US Census he emigrated in 1882. I know he is from Sweden but I do not know where as I am having trouble locating his immigration records.
It is most likely that the 2 Olafs are not the same, as yours is listed as being born much later.
There are some public family trees that list my Olaf as being married to an Anna Hanson, but I am not so sure as I can not find any evidence of this. All I know is that on the 1900 Census, it shows that he had recently married an Anna and my guess is he adopted her three children (Alfred, Minnie and Adolph).
His son (or as I believe it Olaf was his father) is Swan John 'SJ' Ek. I have him listed as being born Oct 18 1862 i Kristianstad, Skane, Sweden, so I guess that if Olaf was his Father he would have emigrated from there as well. SJ is my 2nd Great Grandfather. He had many children, my Great Grandfather being Emil Alvin Ek born 1894.
Any information would be greatly appreciated.
Thanks!
