When was the last time you used an abbreviation, either in a location or in the notes or sources portion of your genealogical software?
Is it an abbreviation that others will understand? Or is it something specialized or local that may confuse instead of enlighten? Someone in 100 years might be able to Google the abbreviation, or maybe not.
Most genealogical database programs are sophisticated enough to handle long place names. Cutting words short might only lengthen the confusion later.
