Read their Declaration of Sentiments and look at it through today's eyes:
One of my favorite mystery series is the Seneca Falls Series by Miriam Grace Monfredo
From Berkley Prime Crime:
Miriam Grace Monfredo is a former librarian and a historian. Living in the small town of Seneca Falls on the eve of the Civil War, independent librarian-sleuth, Glynis Tyron is an advocate for women and slave rights. But in the midst of her fight for justice she can’t seem to stop enmeshing herself in murder.

Unfortunately the books are out of print, but used copies are availabel on amazon. And of course, you can always check with your local library.
The major players of the movement and the convention are integrals to the stories and IMHO it weaves history and mystery together for wonderful tales.
