Modern invented name, possibly meaning son of David
Daycen is a contemporary American invention, likely created by blending the prefix 'Day-' with the popular '-cen' or '-sen' suffix found in names like Bryson or Jensen. It is often interpreted as a creative variant of Dyson, which is an English surname meaning 'son of Dye' (a medieval diminutive of Dionysius).
