I posted a query to the fiddle-List and received information from Jim Nelson, who kindly posted above, and the following from Dr. Howard Marshall:

Roy Wooliver (or Woliver) has been dead for perhaps 30 years. Wooliver was somewhat of a transient, in and out of trouble with John Law, but generally he was "from" the area just southwest of St.Louis in the northeastern apron of the Ozarks. Gene Goforth tells some good stories about Wooliver's antics and scrapes with the law. All who knew Wooliver remarked on his amazing fiddling, in both style and repertory.

Wooliver occasionally played over various live AM radio shows in the St.Louis area, including Cousin Emmy's show over KMOX.

Hartford met Wooliver in the late 1950s and did a lot of home recordings of jam sessions with Wooliver with Clifford Hawthorne, and others. Hartford's version of Roy's "Money Musk" (which is a good deal different from the usual take on this great tune) is on Hartford's new CD called "Hamilton Ironworks" and maybe even on Gene Goforth's Rounder CD a couple years ago called "Eminence Breakdown."

Wooliver was the main fiddling mentor to the great Gene Goforth of High Ridge, MO.

Wooliver was quite a character and a great fiddler who liked tough hornpipes in the flat keys as well as the standard things you might hear other places. His fiddling style fit in with the general central Missouri style, and was not an Ozarks style.

Cheers, Howard Marshall

Bardford again - hope this helps, Molly.
