I normally look at the profile just before or after (that was most likely imported with the same gedcom) and see if they need a child added and repurpose the profile.
for example he is Gray-26080 so i look at Gray-26079 and Gray-26081, and in this case found more unknown Gray’s that are unsourced undated unconnected unlinked.
so need to expand the search some more to find some Gray’s in that branch (as these profiles have a PM) that need a few children.
if they were orphan profile and unlinked, no prior history to them, you add them to this
