I've noticed a few things that are very similar that we have touched on in the Lord of the Rings.
There's a lot of talk about ring givers. That being people who give freely of their riches. This matches with the hobbits giving of gifts and of the sayings of the high one. also the term "ring-giver" makes me think there is something more significant about rings in this culture that I'm not seeing. This might add something more significant to the value of the One Ring.
Also the long lineage and the historical value of each person in that lineage makes Beowulf a lot longer than it would be if it just concentrated on him. Definitely reminds me of that Monty Python skit. It also reminds me of the hobbit lineage that just seems to keep going in LOTR.
