Ladislaus I of Hungary - DNA confirm

My 37th Great Hrandfather

I suppose me and you are also related some how. I just need to figure out how but I dont know how

Ladislaus I is my 28th Great Grandfather and my 27th Great Uncle.

Ladislaus I of Hungary is my 25th great grandfather.

I have also had a DNA test and share an 'exceptional' (their words) amount of DNA with Ladislaus 1.
788 cM's (that's a lot for such distance) which means it must be a direct ancestor from what I can gather.
So now to find the family tree!
I'm in Australia but first born - all family (both sides) were in Croatia, Slovenia, Austria, Germany and Czechia.
DNA says Balkans too.
If anyone has any of these names in their tree that would be awesome!
