Have you locate a place of birth?
I would say that a TOKARCZYK is a good spelling.
Any of the Tokarczyks that came thru Ellis Island to America related to your ancestor?www.ellisislandrecords.org
Have you these sites for research?www.pgsa.orghttp://maxpages.com/polandwww.halgal.comwww.surnamenavigator.orgwww.polishroots.com/genpoland
Polish alphabet does not have a V only a W so the spelling Stevarsky might be STEWARSKI, STAWARSKI, or STAWIARSKI.
