As I posted last year, above, there are two intriguing 17th century allusions to "Tom a Lin" and the supernatural in one breath:

1621 Richard Johnson, History of Tom Thumbe: “Nor shal my story be made of the mad merry pranckes of … Tom a Lin, the Divels supposed Bastard.” Also mentions “the lusty Pindar of Wakefield.”

1627 “Tomalin” is a fairy in Michael Drayton’s Nimphidia, the Court of Faery (1627).

These are the only authentic such references I was ever able to find in years of on-and-off research.
