Is the marriage valid if the uncle, in the wording of the contract, said: "I marry you to the daughter of my brother," even though she is not his daughter, and he was acting as an agent for the girl and her brother, and her father was deceased?

If the paternal cousin of the woman's father acts as an agent for the closest guardian (the brother, if the grandfather is not alive), and the offer and acceptance occurred between them after the wife was designated and two witnesses were present, then the contract is valid. The statement of the officiant, "my brother's daughter" instead of "my paternal cousin's daughter," does not affect the contract as long as the wife has been designated by the guardian's statement, "I marry you to so-and-so, daughter of so-and-so."
