I'm not a Woolsey researcher. I sometimes answer GenForum posts the way normal people do crosswords. I use the daily search for messages a month old having the words "Please" and "help" in them. It gives me a nice collection of puzzles. That is how I found yours. By rare coincidence, I also do obit lookups in my county, Stanislaus. Yours is the first post I've found in a couple of years where my two GenForum interests intersected.
So - I am as much in the dark about W. G. as you are, and if you have access to the census, you have as many resources as I do. Would you like me to look for your grandfather's obit?
