LOL, I know!!
Don’t remind me… there are 35 entries for OG Kush and I cross checked everyone! 
…and chased after all of the clones…
Seedfinder looks rather ‘retro’ now and unfortunately the newer breeders don’t seem to post info there but I haven’t found anything better.
It never ceases to amaze me that there are so many unknowns in the lineage of most lines… … and they’re not that old…
Any other line of inquiry you would expect these levels of uncertainty at 200 years… not 20!!
Like that old saying… “if you can remember the 60’s you weren’t there”…
