I’ve needed some actual ~1800 given names for some time. A fellow named Douglas Galbi has some very useful lists at galbithink.org.
He has separate lists of surnames, male and female, which list names by their descending frequency of occurrence. It’s a great help.
Another resource is the list of names of those aboard the prison ship Jersey, in New York harbor. You can find that and more at http://www.usmm.org/revdead.html
