From memory but i think it is extremely rare for Haemophilia to pass from Father to son - it is always passed through the mother I believe.
However I believe that daughters of haemophiliac fathers always inherit the gene. Leopold Duke of Albany did not pass the disease to his son Charles Edward DUke of Saxe Coburg Gotha however his daughter Alice Countess of Athlone was a carrier and her son did have the disease whilst her daughter wasn't a carrier.
Oh! Thank you so much for correcting me! I won't make that mistake again. I'm sorry.
