Researching a picture - Part 1 - Sandberg girls in Wausa, Nebraska

In 2007 when we started doing family history research we visited my mothers cousin, looked in photoalbums and read old documents.  A whole bunch of the photographies are still unidentified but on a very  few of them someone has written names. Names I have never heard before.

This will be the first post of a few with identified people. I dont know if there is a relationship with me, but maybe someone will recognize any of the persons. So, lets start with thisone of Selma, Olga and Augusta  Sandberg. From knowing thier names this is what I have come up to:

The Sandberg/Olsson family of 1889 (Peter, Kersti  and Selma) immigrated to the USA. They arrived in New York on May 16 1890 with the ship Gallia.

I was lucky enough to find them in the differnt census and when re-looking at the facts a couple of months ago I found that someone had added information at findagrave.com. NICE! Thats one thing I have learnd over the few years I have been doing genealogy let the people rest for a while.

Are the Sandbergs related to me? I dont have the answer yet, I havent found any connections so far. The only little piece that make me somewhat suspect there is a connetion (which also could be only two familes knowing eachother) is the name Darlles who they named one of the sons born in the US. Darlles
is a VERY uncommon name in Sweden, infact, the only person I have ever heard of having that name is my aunts husband (and it was thier son who had inherited all those pictures from his parents). So, maybe, maybe the connection is on his fathers side.
