Tyleik is of Norwegian origin, derived from the Old Norse 'Tyldrík', which consists of the elements 'tyllr' meaning 'to make an effort' and 'ríkr' meaning 'rich'. It was popular among medieval Norwegians but has since become quite rare. The name is not widely used outside Norway today.
"Tyleik experienced a steady rise in popularity from 1995 to 2003, with birth numbers ranging between 5 and 7 each year, culminating in a total of 34 babies named Tyleik during that period."
