And, of course, there's also online sites (like Ancestry.com, Family Search, and...... SF Geology - which is a GREAT PLACE to find lists of students who graduated from various high schools and colleges - I even contributed a few lists myself).
Ancestry is AWESOME... E.g., seeing my Dad's WWI Draft Card made me burst into tears!!
I also found distant relatives of distant relatives....you know what I mean...
Unfortunately, Ancestry is quite spendy...but I am currently sharing membership fees with a former St. Cecilia classmate, because we cannot afford it individually.
Those of you on WNP might consider also sharing a membership with a fellow WNP-er.
