Can someone help me determine what the most likely ports of departure would be for people who departed from Lithuania to the U.S. around the turn of the 20th century. Both of my in-laws were from the Kaunas area. From what I find in immigration papers, my father-in-law, Adam Petraitis departed from Libau (sp?) Lithuania abord the steamship Birma of the Russian-Asiatic Steamship Company in 1912. He is identified as a subject of Russia. My mother-in-law, Adela Dawidowicz, departed Leteau (sp?) on steamship Kursk of the Russian-American line in January 1913 arrived at Halifax. From what I can see on a map of Lithuania, Libau/Leteau - as shown on their immigration paper - may well be Libau, Latvia, rather than Lithuania. Can anyone point me in the right direction to further this research?
