Timeline Event
Thengel lives in Gondor
Event Type: General
Age: 3rd Age - The Stewards
Years: 2923 ~ 2953
Description:
'Thengel, his [Fengel's] third child and only son, left Rohan when he came to manhood and lived long in Gondor, and won honour in the service of Turgon.' [...] When Fengel died [2953] the Rohirrim recalled him, and he returned unwillingly. Appendix A, II, The House of Eorl
Contributor's two cents: If one takes the late twentieth-century age of eighteen as 'coming of age,' that would have Thengel leaving Rohan in 2923, but Tolkien does not state explicitly how old he is when he goes to Gondor.
