How is the importance of the family emphasized in the uri ceremony in things fall apart?

Not only the parents and immediate relatives were invited, but also the distant group of relative kinsmen called umunna. Men, women, and children were all invited. Palm wine was brought to the whole family. The married women wore their best cloths, while girls wore ceremonial attire of red and black waist-beads and anklets of brass. Kola nuts were shared. There were also many toasts between the two families involved, both pronouncing the graces of the other. The ceremony lasted far into the night, with dancing at the end, and hired musicians.

Finally when the guests left to go, they paid courtesy visit to prominent men, such as Okonkwo, who also gave a present of two cocks to them.
