最终，姐妹俩的第一段歌词消失了。 “祝你生日快乐”，这首唯一的生日歌完全取代了姐妹俩原来的歌曲“家早上好！”。

　　After Mildred died in 1916, Patty, together with a third sister named Jessica, sprang into action and took Mr. Coleman to court. In court, they proved that they, indeed, owned the melody. Because the family legally owns the song, it is entitled to royalties from it, whenever it is sung for commercial purposes.

　　玛德里德于1916年逝世后，柏蒂与其另一个妹妹杰西卡出面将科尔曼先生告上了法庭。在法庭上，她们证明，实际上她们拥有这首歌曲调的版权。由于这首歌曲的法定版权属于希尔姐妹家，它便被赋予了皇权，无论何时这首歌因商用目的而被唱的时候，其皇权总是会受到保护的。
