Dear Mr. Nash,
Thank you for posting your request on History Hub!
We suggest that you contact Beaver County Genealogy and History Center. Their website indicates that they have family history, historical photographs and even early 19th century newspapers. For more information, please contact the Center at firstname.lastname@example.org.
Since Captain Poe’s family history includes numerous prominent figures from history, many of whom have photographs posted online, it is possible there is a photograph of him in existence in a private family collection. If you have an account with Ancestry, you may be able to reach out to a descendant via their message boards. Instead, you may wish to check your local library as many library systems subscribe to these sites, making them free for their patrons.
We hope this is helpful. Best of luck in your research!
