Name these strains - I only have abbrevations

My mate Trevor bought some teen clones from a dude with just abbreviations. He forgot to call the dude back. I only have abbreviations and there are at least 150 strains.

PCK - ?
MD - ?
PU - ?
Mike's BD - My guess a sativa. Stringy thing. Mike's Blue Dream???
Alien OG Chemdawg. Is it just Chemdawg or Chem D and Alien OG? Does not want to get too tall too?

Pu- purple urkele
