My mother is the grand daughter of Henri d'Orléans, Count of Paris (1908-1999) and of his wife Isabelle de Orléans e Braganza

My mother's DNA has been tested. 10 of my autosomes over 24 have both alleles that are the same as my mother's ones, which should be impossible. Indeed, normal people have only one allele from their mother and the other one from their father.
I was told by directors that can happen in families in which there are much intermarriages between cousins to maintain blood and power.

I am consanguineous.

My mother is Martine Marie-Lyse CADET.

My mother top 20 countries of ancestry (best matches are Northern Ireland and Norway)

Isabelle de Orléans e Braganza maternal line was from Hungary, the Balkans, and Northern Europe. Her mother's name was Élisabeth Dobrzensky de Dobrzenicz.

Serbia was my last match over 20 on my results and now it is number 7 over 20 on my mother's results. Moreover, there are in my mother's results Budapest, Hungary and a match for Romania, "Szekler, Romania", Szekler are descendants of the Magyars and said to descend from Attila and from the Sumerians. Szekler are the people of what was Transylvania. They are the people of the Vampires lol. More seriously, their Royalty is said to be connected to Jesus, they would be the Merovingian bloodline. Their coat of arm are the Sun and the Moon.
