Sybil de Torrington was most probably married to Henry de Umfreville of Devon and Glamorgan Wales. They had a son Henry de Umfreville of Devon who inheritted 1/5 of Great Torrington, Devon after the death of his uncle, Matthew de Torrington c. 1227. The proof of this is in this 1229 Calendar of Patent Rolls record. https://archive.org/details/patentrollsreig03lytegoog/page/819/mode... Henry Umfreville died by 1233 and his son gave homage for his father's 1/5 share of Torrington in 1233. https://books.googleusercontent.com/books/content?req=AKW5Qad3TCdQ0... Sanders made an incorrect while guess that Gilbert's father was Richard de Umfreville in "English Baronies", page 48.
