Under the premise of non-consanguineous marriage, two people with the same surname can marry. There is no law in our country that people with the same surname cannot get married. Marriage is permitted as long as the two parties are not directly related by blood and are not related by collateral blood within three generations.
First, the origin of the saying "the same surname can not marry"
In ancient times, when transportation was difficult and population mobility was low, a surname was a family or tribe. The people in the tribe all belong to the same ancestor and are closely related by blood.
Coupled with the high probability of marriage with the tribe, most of them belong to the marriage of close relatives, resulting in a high probability of disease and easy death of the child. So there is a saying that people cannot marry each other with the same surname.
This shows that in ancient times, the reproduction defects of the next generation brought about by the marriage of close relatives have been found, which is a symbol of the progress of human civilization, but this statement is no longer suitable for the current social situation.
Second, the same surname can be married reasons
(1) At the national level, marriage between close relatives is prohibited (that is, marriage between two parties who have a common blood relationship for three generations or less), but there is no provision that marriage with the same surname cannot be married. So legally, marriage with the same surname is allowed.
(2) The same surname has no adverse effect on both parties to the marriage and the offspring of both parties, as long as both parties are not close relatives and meet the marriage requirements, they can be licensed to marry.
