I had previously posted Bertha Haaland's trip in 1912 on the Lusitania.
Ole and Mari Finnestad's great great granddaughter, Rose Kolberg had done some research that indicated Rachel had also been on the Lusitania.
It appears Bertha and Rachel had traveled together on that particular voyage. I located the passenger record, (below) however, when I attempted to bring up the original ship's manifest with the passenger list, the S.S. Hamburg popped up instead and Rachel was no where to be found.
I went through the passenger records where I found Bertha and on page 10, found Rachel Vallem (#28).
Here is another photo of the Lusitania.
