I want to thank everyone who responded to my inquiry about NYC wards. I have learned so much great info :) I have been able to map out where my guy lived, worked and where he was buried. With the info y'all provided, I am able to say with a certainty that the man in the 1836 city directory (who is also listed in the 1840 census) is one and the same as the man buried at Green-Wood.
