In China, different Zhou families have their own word generation, which may change with time, so the word generation you are looking for may not be suitable for your Zhou family.
If you don't know much about family history, I suggest you seek help from the elders, relatives or the Zhou clan association, who may be able to provide more accurate information. At the same time, you can learn more about your family background and word generation by consulting relevant materials and participating in the activities of the Zhou clan association.
