I'm not sure that I really get what's going on here. Presumably the paragraphs are from different bottles from different eras from members of the same family? I'm not really sure. There seems to be a thread running through the stories, but there's no real tension or escalation. The last paragraph felt more than a bit narmy to me, as the "Enter the deep" bit came out of left field, only to be repeated a dozen or so times.
I think this is a potentially good idea for a story. This needs some modification, however. First, I would try to make the individual messages more apparently distinctive. Putting them in boxes ("> wordswordswords") would go a long way to making it clearer, and breaking up the paragraphs would make it more readable.
Second, try to make the characters more distinctive. Other than being told, there's really no indication that these are different characters. Someone born in the 1800s would have a very different writing style (assuming they can even read and write) and outlook from someone in the modern day. Make these more apparent.
Also, try to weave the horror aspect into the story more. As it is, it's a bunch of horror tropes in snapshots of characters that I don't really care about.
Honestly, this doesn't read like a bottle. Maybe more of a diary of some kind, but even then, it's not particularly compelling or realistic. If you haven't already, I would check out Survivor Type by Stephen King as an example of how to do lower-key horror via diary.
When you feel like you've got another draft, feel free to repost it in this thread or come onto IRC and discuss it.
