When possible, I give name information found in works by various German, Lithuanian, Polish, Russian, and Ukrainian experts. If I can find no expert analysis of a name, I check dictionaries and other sources for information on plausible roots for that name, making it clear that this is just my interpretation of what I find in those sources. Information from a specific family's history is likely to tell you more about why and how a particular name came to be associated with that family than generalized information typically given by name experts. I cannot guarantee the accuracy and relevance of the information I give, precisely because I have no access to detailed materials on individual persons or families. The circumstances that caused your family to use a name might differ from those that applied to another family's use of the same name.
As of 24 October 2009, I no longer include e-mail addresses in posted name analyses. If you wish to contact the person who asked me about a particular name, write me and I will forward your note to the most recent address I have for that person. Of course, I cannot guarantee that person will receive your forwarded note, or if he/she does, will answer it.
