Alright, I did some searches but I guess my search-fu is weak. I know there was a thread on this recently, I remember reading it. I'd like to know what settings are required to disable migration. I would like to play a fortress which utilizes only the original 7 dwarves and their children. A single migrant wave is acceptable if it is unavoidable.

The only things I found when searching were a few 2007/2008 threads which intimated some link between the BABY_CHILD_CAP token and immigration, as well as obviously POPULATION_CAP. I also saw warnings that setting POPULATION_CAP too low will cause it to be ignored.

Can someone help me out here?

Yeah its pretty much all in the wiki under 'Init'. Go to your init, its a text file somewhere in your data folder and lower the immigration thing from 200 to 7. As long as none of your guys die my understanding is that you won't get any immigrants. Check the wiki for further help.

Uh, thanks? I did, of course, check the wiki before posting... none of the questions I asked are answered in the wiki. The wiki's advice is to set the POPULATION_CAP to 15-20 below your target number which is meaningless as I would like NO migrants at all. I have seen in other threads indications that setting POPULATION_CAP too low (to 7, for example) will simply make dwarf fortress dismiss it and proceed as normal. I don't know if this was a quirk of a previous version or an ongoing 'feature' and that was one of the purposes of posting here.

As for the BABY_CHILD_CAP, the wiki doesn't have any information at all on my question there about it having an effect on migration when set incorrectly. I understand what the notes in the init file say, and what each token is supposed to do, but DF is rife with unintended/undocumented interactions and features. I do appreciate your attempt at helping, I just wish it were more helpful.

Well, if you really want to play without any migrants, you could have a retracteble bridge over a very deep cliff/hole and station all migrants that come over it while you drop them to their death.  I'll see if I can find anything that says what to do for having no migration.

Edit: While I have no idea if this will work, did you try setting the Baby child cap as this:

[BABY_CHILD_CAP:0:1000]

If it doesn't, I'll see if I can find anything else.

That wouldn't serve my purpose even if it worked, because I want the dwarves to have children...

You will always have at least 1 immigrant wave. Even if you set the population cap to 7, it is hardcoded at a minimum of 10 dwarves.
This means that, as long as your current population is below 10, you WILL get an immigrant wave.
The size of this immigrant is not capped. So, it can take your population above the hardcoded 10.

But then again, it's not that hard to kill off migrants. On the bright side, their deaths will send a warning to the Mountainhomes, and migrants will be less likely to come (many deaths = less migrants)

There's been quite a few people who did a hermit challenge. Provided for nice stories

It seems after searching for a bit, there is no clear way to not recieve immigrants (well, I can't find anything).  The only other suggestions I can make to help stop or curb it is to either mod it so no dwarf civilizations are alive anymore in the world (it should still allow you to make a fort without immigrants coming because they're all dead) or just not make wealth since immigration is controlled by that.

you could also embark on an island, but then you wont have any trade...

Use a embark editor to start with 10 dwarves

set pop cap to 10

baby cap left alone

Hmm, I could do this. Which would you recommend? Tweak?

I'm not familiar with them, as I use 40d13 and none exists for that version yet. I understand there is save compatibility between the versions though so I could swap as needed.

Will additional children be born even though the population cap is set, say to ten, and there are already 10-15 dwarves?
Can dwarves who share one same grandparent fall in love and get married?

Yes to the first, as far as I know pop cap only affects migration.

I have no idea for the 2nd one.

[EvilTwin]

that wouldnt be a problem though, as there's dwarves from other grandparents... also, even the first generation after the original embark dwarve's generation will "produce" a lot of youngsters, i think

[blah28722]

oh, you're going to want to do something like [CHILD:3] on dwarves so they don't take 12 years to mature.

I dunno, with only a few dwarves, FPS is really high. A year can pass pretty quickly.
