Not sure if relevant to current discussion but the following Cannan/Cannon births for Cleveland area:

Cuyahoga County Births - Volume 1 1867 - 1873

http://www.rootsweb.com/~ohcuyah2/births/volume1/pg0007.html
Cannan Wm. 164
Cannon Cath 270
Cannon Florence 252
Cannon Lottie 172
Cannon W. Albert 213

I believe chronolgical by page: 164 born before 172 for example.

In Vol. V 1881 - 1884
Camon Lydia 105
