Allow me to echo Maggie's gratitude in your contributions to the profile...I must however disagree with your suggested pre-requisites:
First, profile contests are about recognizing the effort put into a profile (whether that effort is in researching and analyzing new sources, authoring a great narrative, improving the visual presentation of the information, etc.) parents, grandparents, children, spouses, and siblings are their own separate profiles.
Second, if users put their time and effort into making a great profile, I can hardly fault them for not creating 2, or 6 or more other profiles as well, regardless how available the information for those profiles is.
Third, a criteria to have profiles for parents, grandparents, or any other relations (spouse, siblings, children) would potentially disqualify many great profiles, where the individual's kin are not known, from being considered.
Perhaps a contest for 'Family Tree of the Month', where the profiles for a family group are judged as a collective whole, should be considered.
Fourth, (and in a similar vein to the third listed point) there are many individuals for whom there are no relevant pictures (or at least none free from copyright). Adding pictures certainly can increase the aesthetic appeal of a profile and probably gives a profile an advantage in the competition relative to text only profiles, but it should not be a pre-requisite for being considered. As an aside photos already have their own contest.
Fifth, there is already a pre-requisite for "substantial recent contributions" before a profile is nominated. In the case of the profile for Thomas Lawrence, the change history shows the immense amount of work that was done in the preceding month by a number of contributors, (most notably Mary Hammond).
