[Facts] Re: Name gender of PLEASANT
The Social Security data is far from perfect. However, there are at least five boys born named Pleasant every year in the data between 1880 and 1888 and during that period it only turns up with more than five for girls once (in 1886, when there are six girls and 12 boys listed), so in the 1880s Pleasant is indeed highly likely to have been a predominantly male name in the USA.
