As we have already discussed in determining the inheritance pattern of autosomal recessive disorder -

The affected individual in Gen 4th have unaffected parents which shows that it is a recessive disorder. Since males and females are affected and male of generation 1st passes the disease to daughter also means the female of generation 1st is a carrier and the disease is autosomal recessive.
