If Joan was really bron in 1378 then it is clear that as things stand Ralph Trenowith, MP (b1377) cannot be her father.
Perhaps Maude Trenowith b1358 is her mother but with a different father as the WikiTree reference cited for Ralph https://www.wikitree.com/wiki/Trenowith-3 has no mention of a wife other than Jane Basset. However, to confuse matters a daughter Joan, born in 1398 IS mentioned. Perhaps then the lineage is correct and contrary to the GenealogieOnline sources on this profile Joan's DOB should be 1398 not 1378? 1398 does nocely concide with the year of Ralph's marriage to Jane and Maude is supposed to have died in 1380.
Thoughts anyone?
