Take a look in Ellis Island website.There are 2 KELBAs, 2 SVEKLAs, 17 BASARABAs, 4 BASSARABAs,and 4 CUCHRANs. None of them are from Boian. To locate an Ellis Island manifest in One Step use : www.stevemorse.org
I am presuming that you are talking about the historical region Bukovina / Bukowina. It is possible that Boian might be Boyany, East of town of Chernivtsi, Ukraine. www.jewishgen.org/ShtetlSeeker/loctown.htm
Take a look in LDS-Mormons (Family History Center) website for the church records of Boian. You can order the films and gather ancestral information. www.bmi.net/jjaso to familiarize yourself with church wording.
