“My son informs me that it is pronounced “Ash” and is from Old English Latin.”

As a letter of the Old English Latin alphabet, it was called æsc, “ash tree,”[1] after the Anglo-Saxon futhorc rune ᚫ which it transliterated; its traditional name in English is still ash, or æsh if the ligature is included.
I asked him the same question!
