Edward Furey of the Keely Society notes:
We don't know for sure, if Keely visited Sandusky, or simply sent plans requested by the pastor. In some cases, we do know, from letters, that Keely would send plans, and then a local building superintendent would follow and adapt them. In that way costs for construction could be kept down for pastors who wanted an impressive structure. We do know Keely was in Cleveland, while that cathedral (radically altered,) was being constructed.
Keely also designed Toledo's St. Francis de Sales chapel.
