Looks like "Ruzk" to me -- the "R" is the same as in "Russia" and on the last entry you can see several places where this writer wrote a capital "S" and it is very different.
"Ruzk" shows up in column 29. In column 11 there is "Ruzsh" which I would guess is the German word for the nationality "Russian" but this column is clearly for an address. As is 29.
Anyway, convenient of her to get her name right at the top where the column headings are.
