Quickley's gravestone does not exist within Veronaville, so she can't be made playable without the use of hacks. As a result, the only indication of Quickley's existence is provided by the family tree of her descendants. According to her SimDNA in SimPE, her hair was black before it turned grey. Quickley's name might have been a play on the phrase "Quickly I'll let you know".
Mistress Nell Quickly is a character in multiple Shakespearean plays. She is the innkeeper's wife, and later widow, in Henry VI and Henry V, and Doctor Caius' servant in The Merry Wives of Windsor.
