What family name has the moto of "tempore candidior"? (become fairer by time)?

Question

I inherited a ring with a family crest on it. It has the words "tempore candidior" on it along with a family crest. I am curious to know what is the family name that goes with the crest. The crest has a shield and what seems to be a quail above it.

Answer 1

If the quail could possibly be a swan, it might be the Main family crest.
