There is a pamphlet (I think in Manx Museum) SIR JOHN PIERS.—1848.
Appeal to the House of Lords between Sir John B. Piers and Dame Eliza, his Wife, and Sir Hen. Saml. Piers, who wished to Claim the property of the former, and prove the illegitimacy of his children. Privately printed. Folio. Pp. 30.

Sir John Piers resided at Leece Lodge, Isle of Man, where he alleges he was married to Dame Eliza, by Orpen Stewart, a Priest in Holy Orders, 1815. The case turns on Marriage Customs of the Isle of Man, and much curious matter is given.

(quote from vol 24 Manxsoc)
and
The GLOBE was opened in October 1806 in ‘ a commodious and extensive house’ on the Parade, by J. Heuchan and Miss White. it appears to have at once become popular, for in the next month the supper following the Assembly was held there and, a few months later, Irish exiles in Douglas met within its walls for a dinner in celebration of St. Patrick’s Day. This feast, the cost of which was 10/6d. per head, was presided over by Sir J . B. Piers, Bt. , a notorious character who had sought refuge in the Island after the Courts had awarded damages of £20,000 against him for seducing the wife of an Irish peer. Although these damages had caused Sir John to flee to the Island, where he could not be arrested, they had certainly not forced him into hiding; for only the previous Christmas he had been a principal in a duel which took place in Douglas and caused a sensation amongst the emigres, as it was said that his opponent had fired before the signal was given. He denied this, but the seconds became involved, and challenges were soon flying all round the town. With such a chairman and such an occasion Heuchan must have felt a distinct sense of relief when the last of the diners passed through his door on their homeward way.
