From the pages of, "A Directory For the Borough and City of Bath and It's Environs, 1852"

Here's a cool look into the Jennings Family that William left behind. On page 126 are listed eleven Jennings, including two with the first name of William. Obviously, since our William left the country 18 years earlier, these ain't him.

However, what are the chances that one of them is William's dad? Also, take note of the "Samuel", because this is a lead I have for ID'ing Jabez Jennings, but that's another story.

This entire directory is a single PDF file, found at : http://www.bathbmd.org.uk/pod.html, along with links for three other Bath directories for the years 1872, 1895 and 1912. Happy hunting!
