Rextyn is of American origin, derived from English and Scottish roots. It is composed of two elements: 'Re', meaning 'king' or 'counsel', and 'xtyn', a variant spelling of 'kstin', which likely refers to someone who was keen or sharp-minded. Thus, the name Rextyn could be interpreted as suggesting that its bearer is wise or perceptive. It is a rare and unique choice for a given name, offering parents the opportunity to give their child a distinctive identity.
Rextyn is quite rare, with only 19 babies named thus over three years.
