Among the many notable people #LadyRanelagh hosted in London was the healer Valentine Greatrakes (already known to her brother Roger Boyle, as his neighbour).

Both she and her brother #RobertBoyle were interested in the debate around Greatrakes ability (which failed to relieve the suffering of #MaryConway). A pamphlet on Greatrakes was dedicated to Robert Boyle, arguing the former's ability could be explained both naturally & miraculously. (DiMeo, pp. 146-7)

Greatrakes died #otd 1683.
