My friend is having a baby girl (so excited!) and she was thinking of using Matilda Marlena (Tilly for short). Her only concern is that Matilda and Marlena sound quite similar. Are they too similar sounding to be a first and middle combo? And is it too much if her last name also begins with an 'M' (2 syllables). Matilda Marlena M______ 'Tilly' - what do you think?
