Need help finding components - Eagle Libraries

[sideburn]

Hi All,

I have been having a hard time finding connectors in my eagle libraries that match the ones I have on hand.

These are the ones I have purchased:

I think the Adafruit eagle library does contain the JST connector but I am not completely sure.

I have had no luck at all with the other two. Is there a way I can easily modify an existing connector or make my own that matches these? Or better still find one that already exists?
I am using the free version of Eagle.

Thanks for the help.
