My son is an 8th generation Texan. The pervious owners of our ranch was Mexico. We are Native Texans
Got ya' beat, I hold title to land inherited directly from family who gained it from the Spanish (first ever to receive any individual title to that particular piece of land). They left the United States shortly after fighting in the Revolutionary War and worked their way to the east Texas area, got here years before Moses Austin started his settlements.
(Guess I can claim Spanish decent, as they had to renounce their US citizenship and swear allegiance to Spain before they could get the land.)
