Numbers 36:11

For Mahlah, Tirzah, and Hoglah, and Milcah, and Noah
The names of the daughters of Zelophehad, and the same as in ( Numbers 26:33 ) ( 27:1 ) , only the order a little varied, Tirzah and Noah here changing places; there they are according to their birth, here they are according to their marriage, as Aben Ezra thinks; though Jarchi is of opinion, that being thus differently placed shows that they were equal to one another, and one was not preferred to the other:

these were married unto their father's brothers' sons;
so that they were first cousins.
