Women singers in the Old Testament choir?

1 Chronicles 25:4 Of Heman; the sons of Heman: Bukkiah, Mattaniah, Uzziel, Shebuel, and Jerimoth, Hananiah, Hanani, Eliathah, Giddalti, and Romamti-Ezer, Joshbekashah, Mallothi, Hothir, Mahazioth. 25:5 All these were the sons of Heman the king’s seer in the words of God, to lift up the horn. God gave to Heman fourteen sons and three daughters. 25:6a All these were under the hands of their father for song in the house of Yahweh, with cymbals, stringed instruments, and harps, for the service of God’s house; (World English Bible, public domain)

This seems to suggest that the three daughters were among the musicians under Heman, their father, in the time of David. The few other versions I checked said the same thing. The question, of course, is who "all these" refers to. I'm not sure.

Thanks for reading.
