'William (vel Thomas) GRESWOLD ... of Solihull, Warwickshire, England. He married Isabell GRANGE (heir of Thomas). [footnote: Glenn Griswold has John Grange but p.6 of Woodall, 3 Oct 1997, confirms Thomas.]'
I assume that 'heir of' means 'daughter of' (partly based on how the footnote is worded), although this source does not explicitly say so. She could be his grand-daughter, niece or great-niece and still be his heir if there were no male heirs.
