Where to find obituaries online?

I have tried genealogybank and have only found 1 obituary I needed, I had a lot of luck with fultonhistory but it looks like in the cities I need they stopped archiving around the 60s-70s, and I tried newpaperarchive, which again same issue, doesn't seem to go past the 60s-70s.

​

I'm looking for Elizabeth Lorenc (maiden Horvath), Binghamton NY Feb 12, 1898- November 1?, 1976

Elizabeth (Wolfe) Tiffany, Oneonta NY Oct 11, 1910- Apr 29, 1990

June Little, Deposit, NY Nov 9, 1917- Jun 15, 2000

Thomas K Little Deposit NY, Mar 16 1915- May 1 1997

​

Anyone have success looking for obituaries around these timeframes on any specific sites?

​

I have pretty much everyone else's obituaries attached to my family tree up to my 4th great grand parents minus these 4.
