Here’s one for thoughts now, later or never, depending on how you feel about it…
Got any headcanons or opinions about the 3 sisters of Théoden who weren’t Théodwyn??? What they were like, where they were during the events that we’re all familiar with, what their relationship with Théoden was like, etc.? It’s bonkers to me that we know they exist and that he preferred Théodwyn to the other sisters but that’s. literally. it!
Omg what a good question! Thank you for leading my thoughts in that direction. There is SO MUCH to unpack there, and even more to imagine, because as you said Tolkien left us a lot of room there (euphemism of the month). I will allow myself to add Morwen Steelsheen to this reflection, because I think it makes sense to link her to her daughters, and similar questions arise around her character.
But I’m a scientist, so let’s think about this rationally and stay organized. I will answer in four parts (I’m not sorry about it)
1. What the canon actually says
2. What are the possibilities, what must be ruled out and why
3. Why I will NOT be going there with my current WIP pHORSEuasion
4. Freeform headcanons I still have on this matter!
Part 1: Deep dive in the canon
Most of what we know about Thengel’s family comes from a couple paragraphs in Appendix A. I have laid out this information in a timeline, with the following assumptions, which can be contested, but that’s what I chose to work from:
-Only one child is born per year
-There are no twins in the family
-The first child of a couple is born at earliest one year after their wedding
-Ages given assume a birthday on January 1st. If the actual birthday happens after the event in the calendar year, the character would technically be one year “younger”
2905: Thengel born in Rohan
2922: Morwen born in Gondor
2943: Thengel (age 38) and Morwen (age 21) marry in Gondor
Between 2944 and 2947: First daughter born in Gondor
2948: Théoden born in Gondor
Between 2949 and 2953: Second daughter born in Gondor
2953: Thengel (age 48) becomes king of Rohan
Between 2953 and 2962: Third daughter born in Rohan
2963: Théodwyn is born in Rohan. She is described as “a child of his (Thengel's) age” (Thengel is then 58 and Morwen is 41).
2977 or before: Théoden (age 29 or less) and Elfhild (age unknown) marry in Rohan
2978: Théodred born in Rohan. Elfhild (age unknown) dies
2980: Thengel (age 75) dies. Théoden (age 32) becomes king of Rohan
2989: Théodwyn (age 26) and Éomund (age unknown) marry in Rohan
2991: Éomer born in Rohan
2995: Éowyn born in Rohan
3002: Éomund (age unknown) and Théodwyn (age 39) die. Éomer is then 11 and Éowyn is 7
3017: Éomer becomes Third Marshal (age 26)
3019: Théodred (age 41) and Théoden (age 71) die. Éomer (age 28) becomes king of Rohan. Éowyn (age 24) and Faramir (age 36) marry in Rohan
3020 or later: Elboron, son of Éowyn and Faramir, born in Gondor.
3021: Éomer (age 30) and Lothiriel (age 22) marry
Early Fourth Age: Elfwine, son of Lothiriel and Éomer, born in Rohan.
Fourth Age 63: Éomer (age 91) dies
Fourth Age 82: Faramir (age 120) dies
Therefore, we have at the start of the War of the Ring, let’s say in January 3019:
Definitely alive:
-Théoden
-Théodred
-Éomer
-Éowyn
Possibly alive (no canonical death):
-Morwen (age 97, but she is of Dunedain descent, so a long life is possible)
-Her three eldest daughters, with ages between 75 (if the eldest was born right after their parents' wedding, in 2944) and 57 (if the third daughter was born right before Théodwyn, in 2962)
A few extra notes on the canon
One thing that I had not fully realized before, is that Théodred is born and Elfhild dies when Théoden is not yet king. Therefore:
-Thengel technically met Théodred (he was 2 years old when his grandfather died)
-Elfhild, although Théoden's wife, was never queen of Rohan
-When Lothiriel becomes queen, Rohan has not had a queen since Morwen, 41 years earlier, at the death of Thengel in 2980
-Théodwyn was only 15, or going on 15, at that time. (I know that I have read somewhere the headcanon that she cared for Théodred from his birth, which is valid and possible, however in my opinion her age makes it doubtful that she would have been the main carer and parental figure.)
-Théoden ascends to the throne whilst bearing not only the immediate grief of his father, but also the relatively recent (2 years) loss of his wife.
Of Théodwyn, we know that she was “the fairest” and “her brother loved her dearly”. After her husband was killed, she “took sick and died to the great grief of the king”. Théoden then “took [her children] into his house, calling them son and daughter”.
And we learn a little about Morwen when Éowyn is described: “Éowyn was slender and tall, with a grace and pride that came to her out of the South from Morwen of Lossarnach, whom the Rohirrim had called Steelsheen.”
(I must say that I am questioning this past perfect “had called”. It sounds like Morwen is not there anymore, otherwise past simple “called” would have been used. But then, it is hard to pinpoint when in time the narrator is placing themselves in this passage. If referring to Éowyn’s early adult life, it would be a clue in the direction that Morwen is not alive anymore by the War of the Ring, or at least that she is not in Rohan anymore. If referring to an undefined point at the moment of writing in the Fourth Age, it means nothing at all. But we’re now at the level of microscopic details from the text!)
Part 2/4 coming eventually in a reblog!
