Allday Family History
Allday Name Meaning
English: in most cases probably from the Middle English female personal name Ald(i)eth Aldith Old English Ealdgȳth. Alternatively perhaps either from the rare Old English personal name Ætheldæg or from one of two ancient Germanic names Aildag and Adaldag imported to England from France by the Normans. The ultimate etymology in both cases is ancient Germanic adal ‘noble’ + dag ‘day’. Americanized form of German Aldag .
