I am conducting research on the family business of Roosevelt & Son (first hardware and then imported plate glass) and Theodore Roosevelt ancestors.  Any leads would be most appreciated.  I have seen the landmark report on the 94 Maiden Lane building.  Some sources say they had a monopoly on imported plate glass but there appears to be a number of businesses selling imported glass in the antebellum years.  I am very interested in how they transported plate glass and where they stored it.  Besides the 94 Maiden Lane address did they use any other warehouses?  How did they hoist the glass to the upper floors?  Does anyone know about how they sold their product.
