THE KING'S SON 

The Capetian dynasty is known as the House of France, and is a dynasty of Frankish origin, which was founded by Hugh Capet b.941AD. Their parent house was the House of Robertian. 

Cadet branches of the House of Capet, include House of Valois, House of Evreux, House of Bourbon, Capetian House of Anjou, House of Vermandois and House of Burgundy - plus many more.

In modern times, both King Felipe VI of Spain and Grand Duke Henri of Luxembourg are members of this family, both through the Bourbon branch of the dynasty. Along with the House of Habsburg, it was one of the two most powerful continental European royal families, dominating European politics for nearly five centuries.

The YDNA of the House of Bourbon has been determined to be R-P310 > R-U106 > Z381*. This  article on the Y haplogroup of the House of Bourbon provides the details of their analysis, including the three men whose YDNA was used.

Regretably this analysis did not provide details on the SNPs below R-Z381, and only 38 STR markers were shown in the paper that was released by these academics.

Additionally, R-Z381 is a sub-clade of R-U106, just as the House of Wettin Haplogroup is also a sub-clade of R-U106,  indicating a distant maleline relationship between the House of Wettin and House of Capetian was a fact.
