Two titles frequently appear in Shipman filmographies: "The Tiger of
the Sea, The (1918)" and "The Eighth Great Grand-Parent." "Tiger" was
advertised in 1918 by her husband
Ernest Shipman as a seven-reel feature based
on a Nell Shipman script and available to state rights distributors,
but there is no evidence that this film was ever made. "The Eighth" is
the title of the original story on which the Vitagraph production
The Wild Strain (1918) was based. Furthermore, Lauritzen and Lundquist mention another
Shipman-scripted seven-reel state rights offering for 1919, "The Coast
Guard Patrol", but again she was never involved with this title.
