Thank you very much for your response. I have many different spellings. I have for Matthew; Dapkevicius, Dobcavitch, Drabkiewicz, Dapkewicz, Dabkeivierene, Dabkevicriute and in America he used Dupcavage. For Mary (Marie) Bartuikiute, Bartnelkoski, Bartnicka, Bernikas. I can not find any sibling or parents names that could help me with the correct spellings.
Thank you again, I appreciate your help.
