Vidumavi

We don't have any definite dates for Vidumavi's life, but we know that Regent Minalcar sent his son Valacar as an ambassador to Rhovanion in III 1250, and he met and married Vidumavi shortly afterward. So, assuming that she was roughly twenty to thirty years old at that time, she would have been born in about the year III 1225. (Valacar himself would have been fifty-six years old when he met Vidumavi, but as a Dúnadan he aged more slowly than other Men.) The last definite date we have for Vidumavi is five years later, III 1255, when her son Vinitharya (or Eldacar) was born.

After Vinitharya's birth, we have no definite canonical account of her life. In the draft text for Appendix A to The Lord of the Rings (in volume XII of The History of Middle-earth), Vidumavi is stated to have '...lived to a great age, as such was reckoned among her people...'. That source gives two alternative dates for Vidumavi's death: III 1332 and III 1344. Even the more conservative of these dates would have have Vidumavi living well past her hundredth year, a 'great age' indeed.

Vidumavi's name comes from the Gothic language: widumawi, 'wood maiden'. The Elvish equivalent of her name is given as Galadwen, apparently from galadh wen, 'tree maiden'.

We know from a passing mention in volume XII of The History of Middle-earth that Vidumavi had 'children' (that is, more than a single child). We have almost no detail about these children at all, and so we have no way of knowing how many there were, or whether they were sons of daughters.
