The so-called Folger Dowland Manuscript may have belonged to the Dowland family and contains some pieces in John Dowland’s handwriting but the other pieces are unlikely to be by Dowland. Wilson's Wilde is there, but not thought to be by Dowland.
The MS is held in the Folger Shakespeare Library in Washington DC and a facsimile is available on the Musick’s Handmade site (find by Googling) together with MIDI files and transcriptions into modern tablature and grand staff notation, so it's a good source for finding new pieces.
