It doesn't appear in the Inquirer (on-line) but it might be in a smaller paper, like the Ledger that GenealogyBank.com overlooked. Also it may have been in a small local newspaper.

In any case, try the email request to the Philadelphia Free Library since you have a specific date.

Good luck,

Frank

PS There were 1212 LINDENs' "Death Notices" articles/entries in the Inquirer spanning 1831 to 1922.
