In Better Call Saul, what is the name of the law firm founded by Howard Hamlin's father?

The law firm founded by Howard Hamlin's father is Hamlin, Hamlin & McGill.

The Albuquerque firm is commonly abbreviated HHM. Its name reflects the partnership of George M. Hamlin and Charles “Chuck” McGill, with Howard Hamlin later becoming its public face and managing partner. Jimmy works there in the firm's mailroom before qualifying as a lawyer, and Kim develops her early legal career there as well.

The firm is sometimes confused with Davis & Main, where Jimmy briefly works, or Schweikart & Cokely, where Kim later practices. HHM's name also illustrates the long professional relationship between Howard and Chuck, a relationship that becomes strained by Chuck's opposition to Jimmy's legal career.
