Uh, no, around 1840 is precisely when
Amanda was at its first peak of use in the United States. Here are two paragraphs from my column on
Amanda published in 2017:
By 1700, parents in both Britain and
America were naming real girls
Amanda. In the early 19th century,
Amanda boomed in the United States. It was among the top thirty names for women born between 1815 and 1850.
The 1850 United States census included 64,130 Amandas, while the 1851 census of Great Britain found only 545, at a time when the two countries’ population size was similar.
