I don't mind
Harriet. I like
Hattie and
Henrietta more, but I admire
Harriet's stalwart charms.
You could try telling him that names like
Harriet are gonna be huuuuge one day - like the next
Isabella! Also it is a very respectable name - nobody thinks a
Harriet is dumb.
Harriet is smart, chic, and sleek.
