Homer Dale Melder: If the profiles are listed as deletions but still show on the tree, then those are most likely the "deleted in a merge"
I did do some looking around Guilluame ll Van Meldert ... there were a number of incomplete merges (i.e. parent conflicts) both "up" and "down" from his profile. After cleaning those up, then Guilluame's statistics show 259 descendants -- but still no path to you.
I also used the HistorySearch tool (learn more about that tool at this Geni Project: http://www.geni.com/projects/HistoryLink/14021) to check for 'issues' in your ancestors (open the Options and 'tick' the "Include Problem Profiles in Search Results" and "Include Pending Merges in Search Results") ... and there were a number of parent conflicts there, too. After resolving those parent conflicts, your ancestor count dropped from 214 to 195
So, you can see that 'cleaning up' the tree may sometimes result in fewer numbers of ancestors ... but it can also increase the numbers, if a merge "connects" a branch which was previously less complete.
But still no connection found to Guilluame.
