delivered the opinion of the Court.
Congress provided in the Federal Employers’ Liability Act (35 Stat. 65, 45 U. S. C. § 51) that the carrier’s liability in case of the death of an employee runs
“to his or her personal representative, for the benefit of the surviving widow or husband and children of such employee; and, if none, then of such employee’s *400parents; and, if none, then of the next of kin dependent upon such employee ...”
The deceased, residing in Pennsylvania, was a railroad engineer employed by respondent and was killed while engaged in its service in interstate commerce. Respondent’s negligence was conceded. The deceased left no widow, children, or parents. His nearest surviving relatives were two sisters and a nephew, none of whom was in any way financially dependent on him. But petitioner, who was his cousin, was a member of his household and wholly dependent on him for support. The district court rendered judgment for petitioner. 57 F. Supp. 625. The circuit court of appeals reversed, holding that petitioner was not entitled tó recover since there were nearer relatives, though not dependent ones, who. survived the deceased. 150 F. 2d 902. The case is here on a petition for a writ of certiorari which we granted because of the importance of the question.
We assume, without deciding, that the circuit court of appeals correctly concluded that members of the second or third class, irrespective of their need, are not entitled to recover if there survives a member of the prior class. Cf. Notti v. Great Northern R. Co., 110 Mont. 464, 104 P. 2d 7. The liability is not “to the several classes collectively” but in the alternative to one of the three classes. Chicago, B. & Q. R. Co. v. Wells-Dickey Trust Co., 275 U. S. 161, 163. Thus to an extent, at least, the order of priority is determined by relationship, not by dependency. See New Orleans & N. E. R. Co. v. Harris, 247 U. S. 367. Cf. Lytle v. Southern R. Co., 152 S. C. 161, 149 S. E. 692. But the circuit court of appeals went further and applied that principle to determine which members of the third class (next of kin) were entitled to recover. It said that since parents or grandchildren, dependent on the deceased, are left without remedy if a widow or child survives, Congress could not have meant to recognize remote *401members of the deceased’s other kin, similarly situated. It read “next of kin dependent upon such employee” to mean “next of kin, if dependent upon such employee.” Since the two sisters and nephew were the “next of kin” who would take to the exclusion of petitioner under Pennsylvania’s law of descent and distribution1 .if the deceased died intestate, petitioner was barred here.
We read the statute differently.
It is clear that “next of kin” is determined by state law. Seaboard Air Line v. Kenney, 240 U. S. 489. State law governs whether it is necessary to determine if one relative is closer than another, or if a claimant falls within or without the class. But under this Act, unlike the state statutes of descent and distribution, a member of the third class must be not only next of kin but also dependent on the deceased in order to recover. The emphasis on dependency suggests that Congress granted the right of recovery to such next of kin as were dependent on the deceased. And that interpretation seems to us to be more in harmony with the Act than the construction adopted by the circuit court of appeals.
We are not warranted in treating as an antecedent class the nearer next of kin who are not dependent. That would be to rewrite the statute. Congress has created three classes, not four or more. Yet to hold that the existence of nearer next of kin who are not dependent bars recovery by more remote next of kin who are dependent is to assume that the former constitute a preferred class. Congress, however, placed all next of kin in one class. To use dependency as the selective factor in determining which members of a particular class may recover is no innovation under this Act. For the Court held in Gulf, C. & S. F. R. Co. v. McGinnis, 228 U. S. 173, that in a suit brought by a widow as administratrix for the benefit of herself and four children, a judgment in favor of an adult child who *402was married and resided with and was maintained by her husband would not be sustained in absence of a showing of pecuniary loss. Moreover, when Congress made the widow preferred over the parents and both the widow and parents preferred over the next of kin, it barred the deferred classes from recovering by creating a preferred class which could recover. Yet if respondent’s theory is adopted, the nearer next of kin who are not dependent are treated as a preferred class not for the purpose of allowing them to recover but to defeat a recovery by all next of kin.2 It may be true, as was the case in Chicago, B. & Q. R. Co. v. Wells-Dickey Trust Co., supra, that the cause of action may be lost to the preferred class and to the deferred class as well. But that result, though possible, flows not from the nature of the preference but from such circumstances as the failure promptly to pursue the claim. Yet it would be a radical departure from the statutory scheme to do within the third class what Congress has not done between the classes and defeat all recovery by holding that the cause of action vested in one who could not under any circumstances sue. Under this Act deferment of a class is based on the existence of members of a preferred class to whom Congress has granted the right of recovery. We find no compulsion in the policy or language of the Act to adopt a more stringent interpretation when we come to determining what members of the third class may sue.
Reversed.
