I should have pointed to the Yates County NY web site.You should find the history of interest. Possibly, it explains why Haziel settled there.The farm land was good, but the majority of the settlers appear to be of a unusual religious denomination. I hope it is a surprise, it might also offer you a lead. FYI, (80% were from RI and CT) They also list county census records and Warren Cady is listed in 1820 before Yates County was formed in 1823, so he is listed in another county. I do not recall if his Post Office is listed, but his being in the area might have to do with the above. It might answer why Haziel is not listed in CT, and why he moved to Upstate New York. I recently found evidence that my Benjamin Johnson Cady father was Joseph C. Cady and his father was likely David Cady from Northampton Co,PA from CT.
