I have just edited one of my trees on myheritage.
For example:
I was left with two profiles of the surname Mortimer. In order to do this easily, I deleted most of the 'of' 'von', 'de', 'de la', 'de l' ' and any other similar preposition in the various languages. Once I have finished adding each family member of each dynasty or surname I will return the prepositions to their rightfull places.
I have yet to edit all the geographical locations.
Whilst adding matches to my tree, I will list all the duplicate profiles that I have found and there are a number of them.
I only have the MyHeritage Profile, not the Geni profile.
