Re: Zhitomir #ukraine
There are several avenues of research, one is to search The Ellis Island Database:
Put FELDMAN in the surname field, and put the letter "Z" in the town field.
The search will come up with many FELDMAN(N)s coming from Zhitomer (town spelled varioius ways)
Look at each manifest and see who they were going to (on earlier one-page manifests) and on the later two-page manifests, both who they were going to and who they left behind. This may give you crucial data.
Hope this helps,
