NHM has wife's name as Lydia. Jane Norton states that Lydia is not the wife of John Lewis. See “The Welsh Family Lineage of John Lewis” by Grace McLean Moses.

Tradition long had it that the Lewises of Warner Hall descended from a Robert who had a grant from the crown for 33,3331/3 acres, and that Robert's lineage was ancient and Welsh. Tradition, however, was largely undone in 1948 on the discovery of several tombstones on Poropotancke Creek in King and Queen County: "Here lieth interred the body of John Lewis (born in Munmouth shire) died the 21st of August 1657 aged 63 years." Robert was wrong, Wales was right. The line reaches back to Rhys Goch ap Maenyrch, born c 1070, lord of Ystrad Yw. Firm documentation starts with Richard, grandfather of John. Subsequent research into church, land, and emigration records bears all this out convincingly. 434
