Murakami Pirates

I've been doing some research on piracy in general, and found some
very interesting information on the wako, and on the Murakami in
specific. The only problem is that any information seems to stop after
Kuki Yoshitaka's victory in the second battle of Kizugawaguchi and
Hideyoshi's release of his anti-piracy edict. I need to know what
happened to the Murakami in the time between their defeat, and
Tokugawa's rise to power. Did they cease to exist as a naval power
altogether? Also, any information on naval battles in the Seto area
during that time, especially those involving the Murakami, Kuki, or
Mori, would be useful.
I'm afraid I've exhausted all of my resources on this, any help
would be tremendously appreciated.
