What is Applejack's last name in My Little Pony?

Answer 1

Although there is nothing confirmed in the canon to definitively say, it can be reasonably assumed that it is Apple. This can be derived from the naming convention already set up by other Earth Pony families (this is important!) because no similar naming convention has been established by either unicorns or pegasi. The Pie (i.e. Pranny Pie. who is Pinkie's grandmother), Aunt and Uncle Orange (Applejack's aunt and uncle), Mr. and Mrs. Cake, There is the Rich family (Filthy Rich and his grandfather Stinking Rich), lastly is the fact that Applejack even refers to her family as the Apple family, to include her extended family. However keep an open mind as this is purely conjectural, albeit logical conjecture.
