What the note records
Siebert's note identifies “Rev. Rusk” as an Associate Reformed preacher whose property was in what later became Spring Grove Cemetery in Cincinnati. It identifies him as a conductor who saw freedom seekers safely to the Stubbs family at West Elkton and states that he would go through Hamilton at night.
Identity caution: the note does not provide Rev. Rusk's first name. The project has not proven that the man was Balthus/Baltis Rusk. Balthus was a farmer and church elder in an abolitionist Associate Reformed congregation, making him an important lead, but the identities remain separate unless direct evidence connects them.
