During the Revolutionary War, Louisville was founded by a few families that accompanied George Rodgers Clark to the "Falls of the Ohio," on May 27, 1778. Of these first families who boldly erected their cabins on Corn Island was John McManness.
The McManness surname spelling was used in the history books to record this event. However, my research has found the surname spelled in other variations, including but not limited to McManus and McMannis.
Prior to 1900 there was a lack of standardized spelling resulting in surname spelling variations. This is John McManness' will with the surname spelling variation McMannis.
