if my identification (+ of course my assumption re parentage of the Wm father of your ancessor as found by Averil ) is correct then Lucy was prob bapt Bra 17990929 d/o Robt Craine + Margt Quark and thus not quite a spring chicken when she had the first illeg child - thus I'd be looking for an Edward Kewley also around 30 or older which would seem to suggest 4 choices - very occasionally an erant father mentions an illeg child in his will but this is rather rare - much better to hope that Lucy sued in the Ecclesaitical court for maintenance (the Manx museum have a handlist + index - as yet unpublished) of cases that went thro court (liber causarum) tho normally such cases involving illegitimates also get noted with the presentments
