Joan Warren (Trelake) - Birth years and parentage

There seems to be an error of identification here, which has apparently been corrected in the Big Tree.

Joan Trelake's own birth date is questionable - there is no documentation on that point to be found anywhere, and it has to be rough-guessed from the known (approximate) birthdate of her son (c. 1538). She was Sir Ralph Warren's second wife, but he was (as far as we know) her first husband. No marriage date exists either, but it would have had to be after the death of his first wife (c. 1515?) but before the birth of his son.

This provides an approximate birth range of c. 1500-1520 (I have found no confirmation for a date of "1497" anywhere and suspect someone pulled it out of thin air and it got taken as "fact" thereafter).

I would be very uncomfortable with putting Joan Warren Cromwell's birth date any later than 1545 (this is also undocumented), and she may even have been a few years older than her brother (say c. 1535-1545).
