I've come across this interesting debate about Edward, Duke of Kent and his possible illegitimate offspring by Julie de St Laurent quite by chance. I don't know your website but I'll pitch in my contribution by relating that my great great grandmother, Mary Anne FitzEdward, is rumoured in my family to be Edward's daughter. We've been unable to trace her birth registration but from her marriage and death certificates know that she was born c. 1806, came from Clapham, Surrey and her parentage was unrecorded. If Julie was born (as I've read) in 1760 then it's most unlikely she could have borne Mary Anne, but if that date is inaccurate (after all, Edward was born 1767) then it might be more feasible. For a number of reasons I've a suspicion that our Mary Anne had an unknown mother. I also suspect that I'm not going to be able to prove or disprove our family legend. But the prefix of 'Fitz' in those days was indicative of royal bastardy.
