Here is a link to Mary Pickford films on archive.org.
Some of the shorts include DW Griffith’s An Aracdian Maid (1910), The Narrow Road (1912) and A Beast at Bay (1912). These are all about 15 minutes long.
I’d especially recommend some of the longer films such as Stella Maris (1918) and Pollyanna (1919).
