If you look at the Middletown, Connecticut directories here at Ancestry.com, you'll find Andrew and Peter Tocsko in 1905 (image 92), and Peter and Steve Tochko, and Andrew Toczko in 1906 (image 172.) It's likely that they are relatives of Dominik and Rozalia.
Also, in the 1905 directory there are two pages of maps of Middletown in the front of the directory. I did not find any street similar to "Koleyaski." I'm wondering if this is actually a surname and not a street...? There are several men in the 1905 with similar surnames, Kalinaski, for example.
Ancestry.com has Middletown directories ranging from 1868 to 1981. Try browsing (not searching) a few of those. Browsing works better since names can be mis-spelled and the optical character recognition software can be lousy! There are probably more Tocsko, Tochko, Toczko folks listed over the years.
