Last residence of a immigrant coming to the US in 1906 was listed as
Pohorlonty.  Please identify the town and some basic facts.  It is
part of Galacia, an area that in the last 200 years has been listed as
Austria, Poland and the Ukraine.

Perhaps Pohorloutz (= Pohorlauti) as mentioned on:
http://www.bukovinasociety.org/Bukovina-Village-Name-List.html

i.e.
"Pogorelovka
Other names: Pogoryluvka, Pohorylóowka, Pohoryloowka, Pohorlauti,
Pogorl?outi, Pogrylowka, Pohorl?u?i, Pogorl'outi"

mentioning ???????????.

According to the 1910 map as mentioned in my previous comment
http://www.bukovinasociety.org/map1910.html

Pohorlauti was at that time a village with 1.000 - 2.500 inhabitants
("Dorf mit 1.000 - 2.500 Einwohnern").

This map is also available on
http://bukowina.info/index.php (click on "Ethnographic map of Bukowina (1910)").

In order to verify that this is the village you are looking for it
would perhaps be helpful if you could mention the name of the
"immigrant coming to the US in 1906".

Do you know which language he spoke when coming to the US?
