I recently found an old envelope that Albert ROOS of Yonkers, NY received from Stuttgart, Germany in 1896. I want to determine if Stuttgart is the birthplace of Albert ROOS and if this envelope is helpful to someone in their genealogical research. I am interested in using old envelopes and postcards in genealogical research. I have an article in the spring 2009 issue of New England Ancestors entitled Philatelic Genealogy and have started the philgen website (www.philgen.org). I do not know if the letter that was in the envelope still exists.
