I'd suggest you join the Lithuanian genealogy group on Yahoo at:http://groups.yahoo.com/group/LithuanianGenealogy/
It's a much more active group that the one you posted your message on.
Since Lithuanian was occupied by Russia (1795-1918), your Lithuanian place name would be listed as being part of Russia (Russland).
It appears the place name is written using a German spelling (e.g., SCHW). My educated guess is that it is the town of S^veks^na in Lithuanian. It is located southeast of Klapeida and 21 kilometers east of Silute. The 2001 census listed it as having 2,053 inhabitants.
Here is the URL for the town's entry in the Lithuanian Wikipedia.http://lt.wikipedia.org/wiki/%C5%A0v%C4%97k%C5%A1na
Hope this helps.
