I just posted this link on My Page - this is related to the discussion we had this morning at the JBN meeting at Ives Architecture studio.
Here is the info on a Google search and the characters to use to limit the search. Disclaimer: I don't know how old this is nor how effective this still is.
Let me know your feedback!
I also shared with Joel this tool that makes it easy to use Google search for genealogical purpose or when you looking for people.
