Lemon Kush and Dutch Treat

I would love to get some help on these two strains.>

Both of these strains seem to help my pain so I would like to know what the Genetics are.

From what I found out, Lemon Kush is either

Lemon Joy and Master Kush?? Can anyone verify?

I found a place online that sells Dutch Treat seeds but couldnt get a response.

Any help would be appreciated.

Thank you to those that have responded to Lemon Kush.. It does seem most think its a cross from Master Kush and Lemon Joy... But what is Lemon Joy... I have never seen this strain. Anyways, no responses about Dutch Treat. I wonder if its just a made up name. I pretty sure its a Sativa and it really has a smooth taste.
If anyone else has any info, it would be appreciated. Please PM or just post your finds.

Thanks.
