I am having a difficult time finding any family members in Poland. Great grandfather michael Wolochowicz came to the US in 1885 at the age of 16. No record of any other family
Have you found your Great-Grandfather at Ellis Island Records.
If you can find him and if there is record of him on the Ship's Manifest. Then it might/should list next-of-kin.
Sometimes next-of-kin can be a relative, sometimes not.
You might also find the town or area he came from too.
Problem: it will cost money to find out.
Have you done a search at familysearch ?
It is also worth doing a name check at JewishGen
You will have to join JewishGen to do a name search. It's free.
search tip: The first time you search at these sites... only enter the surname. Then if you get too many results you can add more info and do another search.
Check: ancestry. com ... genealogy.com ... polishroots.org
If you would like a few more sites to search... there are quite a few in the Genealogy Resources thread.
