I am looking for some kind of online guide or anything that can help me to find which solvent can be used to dissolve specific compounds.  currently I am looking to see what MgBr2 is soluble in.  any suggestions? I am using THF right now but it appears not to be dissolving that well at room temp.

did you try water 

seriously: if THF doesn't work I don't think you will find a solvent that does work. Maybe DMSO (or methanol if the chemistry allows you to use that)

You can try the CRC, if you have a handy source, or just google it if you're at the computer.  But the general concept is, like dissolves like.  So really, an ionic salt, either dissolves in water or doesn't.  Non-polar solvents aren't the answer to ionic salts that won't dissolve in water.  That just seems counter intuitive to me. 

*[EDIT]*

Oh look, a quick search for it's MSDS lets me know it's also soluble in methanol

yeah I was right
