According to tradition my ggreatgrandmother grew up (as an orphan?) in the home of Rabbi Eliezer of Rozhinoi (I don't know his family name) during the mid 19th century. The Eliezer was probably a relative or in close touch with the Volozhyn family.
Can anyone identify this Eliezer and still better, if anyone has information on his children or "adopted" children who may have grown up in his home.
