Weaver was the son and heir of Thomas Weaver, Esq. of Aymestrey, Herefordshire and his wife Anne Lewis of Radnorshire, and cousin to Richard Weaver (MP) and Edmund Weaver (MP). His father served as High Sheriff of Radnorshire in 1646 and died in 1647. Weaver matriculated at Brasenose College, Oxford on 28 Jul 1651 and was perhaps a student at Lincoln's Inn, 1649.
