Are they completely stationary or do/can they move around in space, as in due to a prior orbit?

I wonder if their trajectories are altered when they absorb new mass.

The mass of the earth can be considered to be concentrated at its center when calculating gravitation attraction for example with the moon. A black hole actually does contain all its mass at its center of gravity exhibiting infinite density called a singularity. Heavenly bodies at a distance can't tell the difference between a black hole or a star of equal mass. The black hole should continue to orbit about the center of its galaxy just as a star would. If a black hole captures a star increasing its mass its new direction (if any) will be a resultant of the combined momentum of the two masses.

Black holes, like any other celestial object, move through interstellar and intergalactic space. No body is stationary in relation to any other, they are all in constant motion, although a black hole, due to its' incredibly intense gravitational field, is usually the center of any system it is a part of.
In fact the leading authorities in the astronomy and astrophysics fields believe the center of our own Milky Way Galaxy is a tremendously gigantic black hole body!

Yes. Black holes "travel". If the universe is expanding outwards (if you can use a word like "out" ! ) then the phenomena like black holes are moving.
Don't think of a black hole as a void, or some kind of a hole--it is a star that has collapsed on itself, and compressed and has become so dense that not even lightwaves are able to escape from its gravitational field. It is still "there", but we are not able to see it, except as it moves in front of stars even more distant from us.

Well no one really understands what black holes do since no one has ever gone into one but there are theory's that you can time travel through them but another good response to the black hole theory is that if you were too pass through a black hole you would be stretched and be turned into dark matter which is supposed to be what the universe is originally made up of

No, they aren't stationary. If they were in orbit of something when they were a star, they will remain in orbit. If they were orbiting around a galaxy (instead of being in the center), then they will continue to orbit.

Black holes can/do move. It is very possible, although unlikely, that a black hole float right past earth, pulling everything in

everyone from grizzly IX on down are basically correct. blackholes like everything else in the universe move. but dont worry it is highly unlikely that our solor system will ever encounter a blackhole.

My sister travels, and she is definitely a black hole.

Yes, they do 'travel'. They will also evaporate.... find out more in wikipedia.com
