I've been following the exchange with a lot of interest because it touches the identities of three relatives I'm trying to trace. 

I have two mystery relatives listed in the family tree passed on to me, siblings of my great-grandmother Dora Koshkin, one a sister, Mayna and the other a brother, Munya.  The Koshkins came from Snovsk, Chernigov, Ukraine.  Most of the family emigrated in the early 1900s but, as far as I know, neither Mayna and Munya came to the US.  I have no records or documents of their lives and for awhile wondered if they were actually one person whose name was transcribed incorrectly in the family tree.  I've since found family photos with Munya and Mayna labeled separately.  :-)

I also have a 2x great-grandfather whose name is recorded as Manis on his son's marriage license and מאניש on the same son's gravestone.  The son, my great-grandfather Joseph Schwartz, is listed on a couple of other family trees where it says his father's name was Emanuel.  A number of posts in this thread suggest that Manis is a derivative of Emanuel but I've always assumed that it was the other way around: that Emanuel was a Westernized rendering of whatever Manis stood for, probably Menachem. I don't know where Manis or Joseph came from but my best guess, at the moment, is Ternivka, Ukraine.
