Re: Nikifor Harlick - Ukraine
You need to locate his precise place of birth among the US documents like naturalization petition, SS-5Form http://ssdi.rootsweb.comhttp://ssdi.rootsweb.comdraft registration form, state marriage application, church marriage record.
No going further with the research without a place name in Ukraine.
Do you know which port he came thru?Try to find his manifest.
HARLICK to me seems an Americanized version of (maybe) HARLIK.
