Check out Mt 12:49, Mk 6:3, Luke 8:19, Jn 7:3,4,5,10, referring to Jesus’ brothers ( adelphos- male sibling in the greek text, not adelphotes - a brotherly relation as in brotherhood).
Also, James, the Lord’s brother (adelphos) in Mt 13:55. Mk 6:3, Lk 24:10, Gal 1:19, Judas in Jude 1, James some more in Acts 1:13, 12:17, 21:18, Gal 2:9, and, James (the entire epistle of).

Best;
