This profile had Joan's birth as "about 1345" but no indication of why; it caused a database error with "wikidata", which had 1347 as birth year (27 April 2019). The wikidata entry had two citations: to Kindred Britain, which did not appear to have any sources, and "thepeerage.com", which is not a recommended source. Lewis had "about 1350" (also not a recommended source). Wikipedia had 1347, citing Cawley's MedLands.
