All the censuses (1900 thru 1940) list Martin & Mary as "Aliens". I believe they never applied for US citizenship. I could not find their arrival in the USA anywhere. .The National Archives would not have any records in regard to same. There is a researcher on this site named "Zemaitis" who will do research in Lithuania at a cost. Writing to Lithuania with specific info, surname, place of birth, is a long shot. By the way, Margaret 'ZINKAITCH" married John J Kurila on 24 Feb 1935 in Kings Co NY. Regards, Carl J aka "Cee Jay" LOL.
