The surnames of the great nobility are always very elegant.
Even within marquis families, the Long Taro Family's surname "Long Taro" is a step below that of the Golden Wheat Sheaf Family's "Golden Wheat Sheaf" in terms of class.
This is also a display of heritage.
The surname of the Golden Wheat Sheaf Family, just decades ago, was still "Golden Wheat."
This is a powerful family, and the reason their surname is not "Barley" or "Little Wheat" is that their family not only has a Little Wheat Greater Elf but also a Barley Greater Elf. Before the Grand Duchy of Sapphire was established, the Golden Wheat Family had already risen by trading in grain.
Later on, following the Sapphire Family, they established a nation and became one of the earliest Marquis families in the Grand Duchy.
However, much like the Pa Pa Family, which split into Small Pa Pa and Big Pa Pa, the Golden Wheat Family also went through a division decades ago.
