There's very little information to go on with this photograph. There is only the name, "Alvina Sauser" and the comment, "Farm in Germany where mother stays when their family were in Germany." I don't know if Alvina Sauser is the the name of one of the girls, or the name of the mother.
The photo ws taken by J. (or F.) Laux, who had studios in on Schloss-Strasse 49, Coblenz, Germany and on Rhein-Strasse 45, Neuwied, Germany. I am guessing it was taken during the latter part of the 1880s or early 1890s.
It's not much to go on. I had a quick peek on Ancestry and there are a number of Alvina Sausers. The problem is I don't know if I should be looking for Alvina in Germany or in the US.
Add this one to the long-shot list!
