[Ger-Poland-Volhynia] August Meier & Siblings - Birth Locations

[Elvin Meyers]

If possible, I would like to establish the locations of the following 4 villages:    Blumenthal
                                Marianna (Michaelowka) 
                                Bulowka                             
                                Dorophiowka
The fifth is Zhitomir, so I'm wondering if they are in the same general area.

Thanks,

Elvin Meyers
