If we are talking about English speaking colonies in North
America before 1776, many of these would work, but some of them just weren't there.
There's a tendency to think all "quality names" were in use in colonial New England, but that's not true.
Chastity was so rare in colonial
America as to be almost non-existent -- and the few real examples I have seen have been Quakers in Pennsylvania, not Puritans in New England.
Virginia was rare and confined to Southern colonies. It's not a name Puritans would have used -- "virginity" per se was identified by Puritans with Catholic saints and so was a word they weren't fond of. All of the early examples of
Modesty in Ancestry.com are from Caribbean islands, not from North
America.
Clarity is for the most part a modern invention -- Ancestry.com has only two possible early examples, both slaves in Barbados. Most reports of "
Clarity" from early records are probably misreadings of bad handwriting for
Charity.
Felicity, Fidelity, and
Verity also were mostly post-colonial, with early examples of
Felicity in North
America mostly occurring among non-English immigrant communities.
Mercy, on the other hand, is an excellent idea, as it was one of the most common quality names in colonial New England, along with
Patience and
Thankful. Silence, Remember, and
Temperance were also used in colonial New England, though the first two were rare.
Temperance was more common and was also found in the Southern colonies as well as in New England.
