No Married Persons

I'd still like to emphasize more the fact that married people wouldn't have been as willing to go. Not just that they wouldn't have been sent, but that they wouldn't have taken up the task if there had been someone important waiting for them back home. I'm not sure how common orphaned or otherwise lonely protagonists were in fantasy-esque books before Tolkien's time, but in contemporary fantasy they definitely seem to flourish.

Also, I agree with Legate that Tolkien's Catholicism might have played a part in it. The first thought I had when seeing this thread was that Catholic priests don't marry so that they could dedicate themselves entirely to their vocation, and it seems plausible that Tolkien had something of the sort in mind, even if not consciously. The Fellowship had to dedicate themselves first and foremost to saving Middle-earth.

Furthermore, Tolkien showed the doubt the Fellowship went through - why didn't I turn back? why did I leave Lórien? why did I come in the first place? - and plot-wise, it would've been difficult to have somebody constantly pining for their spouse. Think how different Elrond's words would have been to anybody who was in love:

You may tarry, or come back, or turn aside into other paths, as chance allows. The further you go, the less easy it will be to withdraw; yet no oath or bond is laid on you to go further than you will. For you do not yet know the strength of your hearts, and you cannot foresee what each may meet upon the road.
