It appears that there were two Swigart's who colonized Richland County. John Swigart arrived about 1816 and married Barbara Ann Young. Michael Swigart, perhaps a cousin or brother, appears to have arrived after 1820. John had a son Luther Martin Swigart. Michael had a son Leonard M. Swigart. I would be interested in identifying the relationship between John and Michael and in identifying their parents. Please post or email if you have information about this.
