I quite like
Märta and
Melker as a sibset.
Um, is it bad that, to me, a sibset like
Zacharias, Zebastian, Zmilla, Ztella and Zamuel has almost a comical element to it? Especially with
Zacharias being the youngest? It's almost like the parents ran out of S-names that they could "creatively modernize" and then, with a big sigh, just made do with any old regular Z-name...
