Yes...
Currently there are alive 3 dynastic (this is what I mean) Wettin males in the Royal House of Saxony:
1. Maria Emanuel, Margrave of Meissen (b.1926), married, no issue; his brother:
2. Prince Albert (b.1934), m. morganatically, no issue; and their 1st cousin:
3. Prince Dedo (b. 1922), no issue.
They are all grand-children of the last King of Saxony, Friedrich August III.
Prince Dedo's brother Prince Timo (d. 1982) did marry 3 times, but morganatically, and left a girl and a boy, whom has in his turn 3 boys. But they're not dynasts and so as males do not belong to the royal house of Saxony, though of course they are Wettins...
The dynastic heir of the Margrave of Meissen is his nephew Prince Alexander (married to Pss Gisela of Bavaria, a descendant of Empress Sisi, with 3 boys and 1 girl as children)...He is the son of Princess Maria Anna of Saxony by her husband the late Robert de Afif, of the Lebanese (Christian) Princely House of Gessaphe...
