Tom:
Great questions!
see Cemetery dates: http://www.hale-collection.com/litchfield-county-cemeteries/618-4-mt-riga-cemetery.htm
Alice Combes’s (Alice III) and my grandmother Alice C. Schwab (Alice I) kept a mt diary 1908-1940. No mention of the flu. No change in # of visiting friends (lots) or types of activities (work, fish, hike); they skipped the 1918 fall hunting trip b/c of being pregnant with Alice II (Aunt Alice Mix of Sharon, CT).
