关于姓氏的讨论的翻译？意译就可以。

Actually, Niu is not a very popular surname in China. The most popular surnames are Li, Zhang, Wang, etc. Out of every ten people I know, many would have Li, Zhang or Wang as a last name. Out of a hundred people, I only know one with Niu as his/her last name. I understand that the three Chinese people you know all have Niu as a last name, it must be fate!

那三个姓牛的是不是一家人？

事实上，牛并不是大姓，在中国姓牛的人并不是非常常见，最常见的姓是李、张、王等，差不多在认识的10个人以内，就会有几个姓李或张或王的等等。在我认识的人中，大概100个人中才有一个姓牛的。我了解到您认识的三个中国人都姓牛，所以说，您和姓牛的人是很有缘份的。所以说和您很有缘份。Actually, Niu is not a very popular surname in China.
