This may or may not be pertinent to you (America3), but for those who have access to the Philly Inquirer if you select DATE = 1918 and enter influenza, you get a slew of names where 'influenza' was part of the obit or naturally, an article. This may help in this query since there's some speculation as to what name she went under.

And yes, there were so many deaths people were placing their dead on the curb for pickup and mass burials. Told to me by my grandmother and mother who lost a son/brother to influenza (2 yoa) but were fortunate enough to have him buried in the family plot.
