Hi
Thank you for your message.
Do you know much about his emigration? The dates, the reason why he left, who he may have travelled with?..etc..Generally more information was given at the port of arrival rather than the port of departure. If you knew which city they arrived at (e.g. Liverpool, New York, etc.), this could be a good place to find more information. -And perhaps even find out an exact place of origin.
