sorry black family honestly but i don't understand your point at all, uditore crime family in 1800s belonged to the same organization of today, sicilian mafia/cosa nostra, it's the same family and organization, there is not any doubt about it, several experts confirmed it, included john dickie and superintendent sangiorgi yes aizukotetsu-kai is probably the oldest yakuza clan, active since the ending or 1800s (1870s/1880s), so younger that italian syndicates (camorra and sicilian mafia, repectively active since 1820s and 1830s)
