I can't provide any info on genealogists in Lithuania but you might try contacting Balzekas's Museum of Lithuanian Culture in Chicago. They have a genealogy section and can provide some help, for a fee and they may be able to help you find a dependable genealogist in Lithuania. Very nice folks-they gave me a surprise by finding my grandfather's application for citizenship to the US. The person to contact would most likely be Karile Vaitkute. They have a website if interested.
