Which asteroid parent do most of the meteorites that land on earth come from? Which asteroid is most likely the parent of the meteorites that I find?

In regards to the most common meteorites...

The most commonly found meteorite on the surface of our planet, Earth, is known by the name "H chondrite". These are stony meteorites with a "high" (H) total iron content.
The comparisons of the reflectance spectra of the H chondrites to the
spectra of several main belt asteroids have yielded a probable parent
body - the asteroid 6 Hebe.
However, 6 Hebe might not be the direct source of the H chondrites but only some sort of ancestor. Probably 6 Hebe collided with another asteroid at one time of his history and larger parts of it were
dislodged into an elliptical near-earth orbit. The resulting swarm of
NEOs, the children of 6 Hebe, are thought to be the true parent bodies from which the H chondrites are derived.

Thanks for taking the time... very cool to know about this. I have collected about a kilo of meteorites now and I have looked a lot of places trying to find this out. I really appreciate it! Deb
