Shoghi Effendi was more akin physically to his great-grandfather, Bahá'u'lláh

Fine-boned, even as a mature man, shorter than his grandfather had been, Shoghi Effendi was more akin physically to his great-grandfather, Bahá'u'lláh. He told me himself that 'Abdu'l-Bahá's sister, the Greatest Holy Leaf, would sometimes take his hand in hers and say "These are like the hands of my father". They were what I call intellectual hands, more square than tapering, strong, nervous, the veins standing out, very expressive in their gestures, very assured in their motions.
