Deletion of Grietje Terburg Rowley

Comment: As far as I can see, her main if not sole source of notability is the LDS hymn "Be Thou Humble". Wouldn't the procedure then be to do an article about the hymn rather than her, just like a notable company's article would be preferred to its founder's article? Nonetheless, not being an expert on hymn notability on Wikipedia, I'm voting based on not seeing either subject meet
