Dr. Loammi Rigdon
A prominent Hamilton physician and Baptist leader whose biography closely matches the “Dr. Rigden” Mark Campbell McMaken remembered as an active Underground Railroad correspondence contact alongside John Woods.
Why Rigdon Matters
In his March 23, 1895 interview with Wilbur H. Siebert, Mark Campbell McMaken described a “Dr. Rigden” as a Baptist physician who was active in Hamilton’s antislavery network. McMaken said that “pretty much all the correspondence would come to Woods and Rigden.” That statement makes the identity of Rigden one of the project’s most important remaining people questions.
Why Loammi Rigdon Is the Strongest Match
Loammi Rigdon fits the central biographical details in McMaken’s description unusually well. He was a physician in Hamilton from 1826 until his death in 1865, and nineteenth-century Butler County histories describe him as a longtime member and leader of the Baptist church. Those facts align with McMaken’s description of “Dr. Rigden” as both a physician and a Baptist.
The project therefore treats Loammi Rigdon as the strongest identification currently available. We are still preserving a formal evidence boundary because no surviving Underground Railroad letter addressed directly to Loammi Rigdon has yet been located.
A Leading Hamilton Physician
Rigdon was born in Pennsylvania on September 30, 1791 and graduated from Transylvania Medical College in Lexington, Kentucky, in 1823. He came to Hamilton in March 1826 and entered practice with Dr. John C. Dunlevy. After Dunlevy returned to Lebanon in 1834, Rigdon formed a partnership with Dr. Cyrus Falconer.
Butler County medical history later identified Rigdon as Hamilton’s senior physician in active practice and recorded him as president of the Butler County Medical Society in 1848. His medical career placed him within a dense Hamilton network that also included Falconer, Dunlevy, John Woods, and other civic leaders.
Building Hamilton’s Baptist Church
Rigdon was not merely listed as a Baptist member. Local church history places him near the center of the congregation’s formation. On December 31, 1841, Loammi and Rebecca Rigdon joined Aaron and Emeline Potter in an effort to establish regular Baptist preaching in Hamilton.
When the congregation was formally received as the First Baptist Church of Hamilton in 1846, Rigdon was listed as a trustee, treasurer, and deacon. The county history later credited Rigdon and Aaron Potter with much of the effort that made the church an established institution.
The Woods and Rigdon Correspondence Question
McMaken paired Woods and Rigden together when describing how Underground Railroad information moved through Hamilton. This suggests a communications network rather than a single isolated station. Woods is independently documented as a major Hamilton civic, legal, railroad, and church figure. Rigdon’s long medical career and Baptist leadership would have given him another substantial set of community connections.
What we still want to find is the paper trail itself: a letter, envelope, diary entry, legal paper, or other contemporary record directly connecting Loammi Rigdon to the correspondence McMaken remembered.
Evidence Boundary
Documented: Loammi Rigdon was a Hamilton physician, Baptist leader, medical-society president, and longtime resident during the Underground Railroad era.
Documented in McMaken’s testimony: a Baptist physician named “Rigden” received Underground Railroad correspondence with John Woods.
Strong identification, still under review: the project believes Loammi Rigdon is the best match for McMaken’s “Dr. Rigden,” but continues searching for a direct contemporary source that closes the identification completely.
