Tillie's Day Off was initially titled "Tillie's Night Out" and was changed by the World Film Corporation because it was filmed during the daytime at Coney Island and they felt that the night out title was not very fitting. Frances Marion wrote many of the Tillie Comedy serials and even appeared in a few of them (Motography Vol XVI No.19).
A title called Aunt Tillie's Elopment was released 11/25/15 and may be the same title by Associated Film Corporation a 1 reel comedy (Motion Picture News 12/5/15).
As far as the other titles during 1917-1918 silent era.com lists two of them as "unknown status"and the others are not coming up in the search engine.
Looks like imdb could use a volunteer to update her filmography with pristine accuracy.
