My great grandfather worked as a Teamster for decades, about 1890 to the 1920s. The US Census, generically said he worked for a chemical company. I just found a 1891 newspaper article that stated he worked for Buffalo Chemical Company. The family lived on Babcock and Seneca St. area for decades. I've been trying to learn as much as I can about this company, without any luck. I've spent a lot of time on Google and in BuffaloResearch.com. Could this company have later become National Aniline? Your assistance is most helpful. Cindy
