Pat,

Don't but the book it is as generic as can be. In fact I never paid for mine and returned it to them. Some publisher in Ohio if I recall, which may now be out of business. Irwin was born in 1853 which means that Charles cannot be his father. I cannot find a father which may mean that Irwin came here from Duetschland or I just cannot find a father. The spelling may or may not mean a thing for Irwin (Erwin).
