Thank you Baba. South Africa has a 100 year non public disclosure as well. The problem with local archives is that you must be in the country, province, city, or town to be able to visit and this is not always possible. I used a very good researcher in South Africa to search family records for me but she could only do so much, the rest is up to me.
What You can do, is to concentrate to Smart Matches and Record Matches. With this two options You can find possibly other researchers with identical branches in their trees.
But, as I've written before, always crosscheck, what You find as good as possible.
Another option, if You are looking for specific persons infos, is to use the Community (https://www.myheritage.com/community). There You can place different questions about persons, photos identifications, translations, transcriptions, etc.
An absolutely 'lucky punch' could be, if You find in the web (otside of MyHeritage) a private website with questionable persons, and maybe a contact to a enthusiastic family researcher.
