Not to discourage further answers but you'll probably enjoy reading these older posts by /u/bitparity while you wait:

To what extent are the noblility of the early middle ages the descendants of the Curiales and nobility of the Roman empire? Were old Roman elites displaced wholesale, or did this class largely adapt to the changing world?

Did any roman patrician families survive the fall of the western empire? Is there anyone alive today that can claim to be a descendant of a roman senator?

And this old thread with answers from multiple users

I recently read how many descendents of the nobles in the Norman invasion still own tons of land in England. So my question is, are there examples of families who have owned land stretching back further, say to the Roman times? Carolingians? Ancient China, India? Or anywhere else in the world?
