It is okay to name a boy not based on his family tree.
1. Family trees are mainly used to record the generations of family members, as well as family history and traditions. Although family members have traditionally been named according to the generation in the family tree in order to distinguish the seniority of family members, in modern society, this practice is not mandatory. Parents can name their children according to their own preferences and wishes, without strictly following the rules of the family tree.
2. In addition, if the family has a tradition of preserving family trees, understanding the generations in the family tree is meaningful to family members and helps maintain family cohesion and inherit family culture.
