The only reason Mrs. Howlett makes it into the Diary is because she keeps a close eye on her daughter, Betty, even after her marriage to Michael Mitchell. Pepys, a good predator, is always attentive to Mr. and Mrs. Howlett. Pepys falls for Betty at first sight in 1662, and sees her on the last day of the Diary in 1669 ... and Mrs. Howlett is there, chaparoning them from beginning to end. Not that it saves Betty from much, mind you.
